In response to the protracted war in Ukraine and the increasingly severe humanitarian situation, China has repeatedly called on all parties to the conflict to exercise rational restraint, strictly abide by international humanitarian law, and avoid attacking civilians and civilian infrastructure.

Geng Shuang said that China plays a constructive role in promoting the political resolution of the crisis and puts forward four imperatives for the political settlement of the Ukraine crisis, that is, the sovereignty and territorial integrity of all countries should be respected, the purposes and principles of the United Nations Charter should be observed, and the legitimate security concerns of all countries should be taken seriously, and all efforts conducive to the peaceful resolution of the crisis should be supported.

United Nations, March 12: Geng Shuang, China’s Deputy Permanent Representative to the United Nations, spoke at a public meeting of the Security Council on cooperation between the United Nations and the EU on the 12th, urging the EU to adhere to the concept of common security.

He said that China supports cooperation between the United Nations and the European Union in accordance with the purposes and principles of the United Nations Charter to make greater contributions to maintaining international peace and security, enhancing the well-being of all mankind, and responding to global challenges. Relevant cooperation should follow the following principles: First, practice true multilateralism. The EU should take the lead in safeguarding the purposes and principles of the United Nations Charter, abide by international law and recognized basic norms of international relations, defend the multilateral system with the United Nations at its core, and promote the unity and progress of all countries under the banner of multilateralism. The second is to adhere to the concept of common security. Security is indivisible. The security of one country cannot be at the expense of the security of other countries. Regional security cannot be guaranteed by strengthening or even expanding military blocs. The legitimate security concerns of all countries should be taken seriously and properly resolved. The EU should work with the United Nations to persist in promoting political solutions to relevant hot issues and resolving conflicts and disputes through peaceful means. The third is to create a common future for mankind. The EU should work with other United Nations Member States to promote this year’s United Nations Future Summit to build consensus, be action-oriented, and send a positive signal to the outside world to open up new prospects for mankind.

He said that the Ukraine crisis is a huge challenge to European security, and the final resolution of the crisis needs to rely on dialogue and negotiation. As an important stakeholder, the EU should be more committed to promoting political solutions, creating good conditions, and building a balanced, effective and sustainable European security architecture. The conflict in Gaza continues and unprecedented humanitarian disasters are still intensifying. China hopes that the EU will make greater contributions to promoting an immediate ceasefire, expanding humanitarian assistance, implementing the two-state solution, and achieving lasting peace in the Middle East. The challenges facing Africa in achieving peaceful development have increased significantly. China expects the EU to shoulder greater responsibilities and support African countries in strengthening capacity building, better responding to risks and challenges, and achieving sustainable development.

He said that China has always attached great importance to developing relations with the EU and is willing to deepen cooperation with the EU in multilateral fields and make unremitting efforts to safeguard world peace, promote common development, and strengthen global governance.

The representative of China calls on the international community to jointly promote equal and orderly world multipolarity

After screening and investigation ddos攻击平台 It is likely to become a new force driving economic development.https://www.ddos444.com/

United Nations, July 16 (Reporter Wang Jiangang) Fu Cong, Chinese Permanent Representative to the United Nations, spoke at the Security Council’s open debate on international order and multilateral cooperation on the 16th, calling on the international community to promote the construction of a more just and reasonable international order, safeguard sovereign equality, and Let every country find its place in the multipolar system, play its due role, and jointly promote an equal and orderly world multipolarization.

Fu Cong said that countries should respect each other, take into account each other’s core interests and major concerns, respect the development paths and institutional models independently chosen by the people of all countries, and not interfere in other countries ‘internal affairs; create common security, be based on the objective law that security is indivisible, and adhere to Resolve disputes through dialogue, resolve differences through consultation, and build a more balanced, effective and sustainable security architecture; Promote common development, promote inclusive economic globalization, accelerate the implementation of the 2030 Agenda for Sustainable Development, and strive to achieve the goal of leaving no country or anyone behind.

Fu Cong called on all countries to uphold fairness and justice, safeguard the authority of the United Nations and international law, advocate a global governance concept of extensive consultation, joint contribution and shared benefits, enhance the representation and voice of developing countries; demonstrate openness and inclusiveness, promote equal dialogue, exchanges and mutual learning among different civilizations, promote mutual understanding among people of all countries, and promote common values for all mankind.

Fu Cong pointed out that the real intention of some countries in the so-called rules-based international order is to create an alternative system outside the existing international legal system and seek legitimacy for double standards and exceptionalism. There is only one order in the world, that is, an international order based on international law. There is only one set of rules, that is, the basic norms of international relations based on the purposes and principles of the United Nations Charter.

Fu Cong said that NATO, as a well-known regional military group left over from the Cold War, seeks to expand its sphere of influence, is keen to create false narratives, add fuel everywhere, incite camp confrontation, and even blame and blame domain name foreigners on the Ukraine issue. This runs counter to the international community’s efforts to promote peace and talks. History has fully proved that wherever NATO’s black hands extend, turmoil and chaos appear. China advises NATO and some countries to reflect on themselves and stop being troublemakers who harm others and undermine common security.

Fu Cong said that common development and common security complement each other and are the foundation of a good international order, in which development is the overall key to solving all problems. Some countries generalize the concept of national security, build small courtyards and high walls, impose indiscriminate unilateral sanctions, and disrupt the global production and supply chain, which will ultimately lead to a situation of double lose and multiple lose. The international community must resolutely resist this erroneous practice.

Fu Cong said that Chinese leaders followed the trend of the times and proposed the Five Principles of Peaceful Coexistence, which fully reflected the spirit of the Charter and created the basic norms of international relations that countries, big or small, strong or weak, regardless of East and West, should respect each other and treat each other as equals., also provides an important ideological foundation for promoting the development of the international order in a more just and reasonable direction. Chinese leaders ‘proposal to build a community with a shared future for mankind is an inheritance and promotion of the purposes and principles of the United Nations Charter and the Five Principles of Peaceful Coexistence under the new situation.

Protein is the source of life and constitutes the cell tissue.

  Protein, the source of life, how much do you know? Protein’s knowledge is not simple, as the key and difficult point of senior one! Today, I will take you to find out and unlock the mystery of protein!In view of the actual needs of society, Antibody Discovery We need to change some original problems to better serve the society and benefit people. https://www.alphalifetech.com/

  

  Protein is the basic substance of cells and tissues. Without it, there would be no life. They are composed of amino acids, and through different sequences and structures, they form an ever-changing protein. This is like Lego of life. Every amino acid is a building block, which is combined to construct the diversity of life.

  

  Protein has various functions, from structural support to catalytic reaction, from transporting substances to signal transmission, and they are indispensable roles in cells. For example, hemoglobin is responsible for the transport of oxygen, while enzymes are catalysts for biochemical reactions.

  

  The synthesis process of protein is also very interesting. The process from transcription of DNA into mRNA to translation into protein is called the Central Rule. It reveals the flow direction of genetic information and is the key to understanding life phenomena.

  

  The structure and function of protein are closely related. The primary structure is amino acid sequence, the secondary structure is partial folding, the tertiary structure is integral folding, and the quaternary structure is the combination of multiple subunits. These structural levels determine the function and stability of protein.

  

  Protein is the cornerstone of life. To understand them is to understand the mystery of life. Through today’s study, I hope you can have a deeper understanding of protein and lay a solid foundation for senior high school biology!

Slow down the clock of life

  Life is a fleeting moment in the river of time, mankind do everything possible to seek forever and everlasting, but did not think, in fact, as long as the pace of their own slow down mentality flat, live in the present, then life will naturally become long and distant .Therefore, this is the choice pu-erh tea The reason, there is no denying its positive impact.

  

  When I did not write a magazine before, I did not know that the time had come in advance. A draft of March or even April has been prepared in January. In the draft of the forum while watching the side gripped, his year has not yet ended, did not make a point, there people work has been a year, almost equal to the end. Years here, was actually can not wait to catch up with the speed of flight, how to make people panic?

  

  The length of time is defined by man himself. 365 days a year, divided into four seasons, twelve months. Here, people always catch up with me like the game, to see who can one day into a day. Our ancestors know, if the decade into a year, we will so impatient it?

  

  Days not used, can only be used to recover. Self has no intention to enter this door, it fell into such a turbulent swirl. Calendars and clocks on the numbers can only represent the past, because today to do, is already the future. Obviously is the spring, but the men have been doing non-stop fall thing.

  

  There is nothing worthy of gratification, no reason for youth just a short length of a bit like others. What is the use of walking in front, time falls behind, urging the old soul and face it in vain.

  

  The fast pace of modern people, nothing more than to speed up the clock of life, their own pressure and persecution of a way, only to more fully squeeze the juice of life to obtain value and fame. But I see it is faster and more leave no room for the consumption and flight. How, a ton of gold can be exchanged for even a second time?

  

  Americans always run in front of the world, even spend today are tomorrow, the result? The financial crisis has finally shattered this myth of early consumption, punish all activities contrary to the laws of nature.

  

  Beijing, then, a little leisurely. People live I, a spring vegetation, how short and beautiful time. If you can walk, why should anxious to run, miss the scenery all the way? Note that the front is not another spring, but has been waiting for you to close the end of life.

  

  Tomorrow’s thing is done today, and next year’s event is finished this year. So ahead of the outstanding achievements and efforts, but is a result of the advance of life.

  

  What is a rivers and lakes years reminder, juvenile children rivers and lakes old? This is the helplessness of life rather than enjoyment.
