As the largest military conflict in Europe since the 21st century, the conflict between Russia and Ukraine has led to a spiral deterioration of the global and regional security situation. On the one hand, NATO led by the United States continued to deliver weapons and equipment to Ukraine and accelerated the pace of military and personnel expansion, which strongly stimulated Russia's security nerves; On the other hand, in response to NATO's military pressure, Russia is considering taking countermeasures and readjusting its military deployment. The tension on the European continent is increasing, so that Russia warned that the risk of nuclear war should not be underestimated. The root of the Ukrainian crisis is that NATO led by the United States adheres to the Cold War mentality, indulges in zero sum game, is keen on camp confrontation, and tries to pursue its own absolute security at the expense of the security of other countries. Facts have proved that mankind is an indivisible security community. Only by adhering to the concept of common, comprehensive, cooperative and sustainable security, firmly safeguarding the international system with the United Nations as the core and the basic norms of international relations based on the purposes and principles of the Charter of the United Nations, can we build a balanced, effective and sustainable global and regional security architecture. NATO accelerates military expansion Since the escalation of the conflict between Russia and Ukraine, NATO led by the United States has taken a series of actions to intensify pressure on Russia, making the global and regional security situation highly tense. First, provide large-scale military assistance to Ukraine. Since February 24, the United States has pledged to provide about US $3.7 billion in security assistance to Ukraine. The US government is requesting Congress to approve an additional US $33 billion to assist Ukraine, of which US $20.4 billion will be used to provide military and security assistance to Ukraine and support the United States to cooperate with NATO allies and partners to strengthen European security. U.S. Secretary of defense Austin also established an international contact group on Ukrainian defense issues with the participation of more than 40 countries, which will regularly discuss and coordinate military assistance to Ukraine. Second, strengthen military deployment. The report released by the British Institute of international strategy before the escalation of the conflict between Russia and Ukraine shows that the total number of troops stationed by NATO in Bulgaria, Hungary, Romania, Slovakia, Poland and the three Baltic countries Estonia, Latvia and Lithuania in its eastern wing is more than 10000. In late March after the escalation of the conflict between Russia and Ukraine, the military strength deployed by NATO in the above-mentioned eight countries has increased to about 25000. In addition, since May 1, 18000 soldiers from more than 20 countries are participating in NATO's "European defender 2022" and "rapid response 2022" exercises in Poland and other countries on the east wing of NATO. Third, multinational defense spending has soared. German Chancellor Scholtz announced a substantial increase in defense spending at the end of February, including the approval of 100 billion euros of special funds, and increased the proportion of German defense spending in GDP to more than 2% in the future. Poland plans to increase the proportion of military expenditure in GDP to 3% by 2023, and the total military strength will increase from 120000 to 250000. Denmark and Sweden also announced that they would increase military spending to 2% of GDP. Finally, speed up the pace of expansion. NATO Secretary General Stoltenberg said many times recently that if Finland and Sweden apply to join NATO, NATO will welcome and ensure their rapid admission. According to an article on the Washington Post website, Finland and Sweden are expected to apply to join NATO before the NATO Madrid summit in June, which will be a major change affecting the European security balance and will greatly enhance NATO's military presence around Russia. Russia is bound to counter it NATO led by the United States continues to expand eastward regardless of Russia's security concerns, which is the root cause of the conflict between Russia and Ukraine. On the ground of the conflict between Russia and Ukraine, NATO has further strengthened its pressure on Russia despite Russia's repeated public warnings, which is bound to trigger Russia's counter-control, intensify the confrontation between the two sides, and make the global and regional security situation develop in the direction of continuous deterioration. On the one hand, NATO has made every effort to deliver weapons and equipment to Ukraine, and the scale of assistance has been increasing. The weapons delivered have also been upgraded from the original individual air defense missiles and anti tank missiles to heavy equipment such as tanks, artillery and armored vehicles, which makes the possibility of "gun fire" and even direct confrontation between NATO and Russia increasing. Russian Foreign Minister Sergei Lavrov pointed out that "NATO has essentially entered a war against Russia through agents, and is arming agents". Its purpose is to use Ukraine to "exhaust Russian military and Russian military industrial forces". If the confrontation between NATO and Russia intensifies further, the prospect will be unpredictable. In an interview with German media in early April, Polish Deputy Prime Minister Jaroslaw Kaczynski said that Poland is open to the deployment of US nuclear weapons in its territory. "If the United States asks for the storage of its nuclear weapons in Poland, we are open to it. This will greatly strengthen the 'deterrence' against Moscow," he said Lavrov previously said that the idea of nuclear war only exists in the minds of Western politicians, but he recently warned that Russia has done a lot of work to adhere to the principle of preventing nuclear war at all costs, but the risk of nuclear war is "serious and real" and should not be underestimated. On the other hand, if NATO expands further to the north, it will mean that northern Europe will become a new front for the confrontation between NATO and Russia. Sweden and Finland have remained neutral for a long time. If these two countries join NATO, it will further aggravate Russia's sense of insecurity. Russian Defense Minister Shoigu said recently that if Sweden and Finland join NATO, Russia will be forced to upgrade the Northern Fleet and equip it with more advanced weapon systems. According to the analysis of the German foreign policy website, Moscow is bound to take countermeasures, which may include the deployment of nuclear weapons in Kaliningrad, a Russian enclave between NATO member Poland and Lithuania, to deter the whole Baltic region, including Sweden and Finland. The safety of not leaving space for others is by no means the right way NATO led by the United States continues to fuel the conflict between Russia and Ukraine, which not only puts Ukraine and the whole of Europe in danger, but also endangers global security and stability. An article on the website of Tokyo diplomatic scholars pointed out that most developing countries have obvious differences with the United States and other western countries on the conflict between Russia and Ukraine, showing "vigilance against intensifying geopolitical confrontation". Guo Yanjun, director of the Institute of Asian Studies of the Chinese Academy of foreign affairs, said that on security issues, some countries represented by the United States are deeply mired in the quagmire of cold war thinking and zero sum game, and are keen to engage in unilateral sanctions and close exclusive "small circles". The vast majority of countries represented by China oppose group politics and camp confrontation, advocate true multilateralism and resolve contradictions and differences through dialogue and consultation. "Who is on the right side of history and on the side of international fairness and justice, the answer is self-evident." China's recent global security initiative has aroused strong resonance and active support from the international community. China's initiative emphasizes that mankind is an indivisible security community, and defines the core concepts, fundamental principles, important principles, long-term goals and feasible ideas for maintaining and realizing global security. This initiative is not only to solve the practical problems of human security, but also to seek a long-term way of world peace. Bambang suryono, chairman of Indonesia's Asian innovation research center, said that unlike some western countries' one-sided pursuit of their own security, China's global security initiative pursues common security and a security concept emphasizing peace and cooperation, which is conducive to the establishment of an international order of mutual respect, equality and mutual trust, and is of great significance to the realization of lasting peace and long-term development of mankind. Shakir Lamai, chief executive of Pakistan's Asian Institute for ecological civilization research and development, said that the global security governance system needs to be reformed, which requires abandoning the Cold War mentality and unilateralism and focusing on cooperative development. All countries in the world should make continuous efforts for a prosperous, sustainable development and a future aimed at building a community with a shared future for mankind. (Xinhua News Agency)
