On the morning of October 30, the US-China summit took place in Busan, South Korea. Trump announced that the world is entering the era of G2. Russia, Europe and Japan have to sit at another table.

Trump used "G2" in social media to describe the meeting before the meeting, although some high tone, but it is true, at present, the global pattern is China and the United States, before Russia, Europe and Japan, who wanted to sit at a table with China and the United States, no longer have this power.

Of course, this status of the "G2" between China and the United States is not obtained for no reason. It is first determined by the economic strength of the two countries. In the theory of political economy, there is a very classic conclusion that "the economic foundation determines the superstructure." Simply put, economic strength is not strong, and everything else is nonsense.

Last year, China's GDP combined accounted for 43% of the total global GDP, almost equal to half of Yangtze, and the pattern of the global economy's dual engine is becoming increasingly obvious.

The China-US tariff war, let the world economy shake the mountains, this China-US meeting, the world hoped, all hope that the two sides can talk about a good outcome, extinguish the smoke of the tariff war, so that the basic disk of the world economy is also stable, other countries can also follow with the dividends.

In the long run, in at least 50 years, no economy can pose a challenge to China and the United States, the only existing variable is how much time China will spend against the United States, becoming the world's largest economy.

Of course, the huge and strong economic strength alone is not enough to support China and the United States '"G2" status. Another very important reason is that China and the United States have incomparable autonomy in political diplomacy. Some people will say that Russia is also a truly independent country, but the problem is that Russia's economy cannot compare with China and the United States.

Although the economic strength of the European Union and Japan is quite strong, these two brothers have almost no say in terms of independence. They all have to listen to and act according to the face of the United States.

When it comes to the Russian-Ukrainian conflict negotiations, the EU is clearly the party and should be involved anyway. But this year, several meetings between the US and Russia involving the Russian-Ukrainian conflict were not invited by the EU. Recently, Trump and Putin approached the meeting in Budapest, Hungary, to negotiate on the ground of the EU, and Trump did not take the EU's meaning.

It is clear that in the eyes of Trump, the EU has become "one side of the road", a role that can not be played.

The situation in Japan and the European Union is almost the same, that is, a part of the United States, this time Trump visits Japan, but the United States is a little unfriendly to Japan.

Russia, which had the most hope of standing up with the United States, together with China, forming a global "triangle" pattern, has also fallen in this recent round of geo-games.

To be honest, now Russia is a foreign power agent, the economy looks good, but the shortboard is too obvious, the dependence on energy exports is very strong, in peacetime, relying on energy exports, the Russian economy has a few guarantees; but once a war is encountered, the economy is dangerous.

After the outbreak of the Russian-Ukrainian conflict, Western countries imposed strict sanctions on Russia, reducing or stopping the import of Russian energy, one hit the Russian economy "seven inches".

At present, Russia can sit in the position of the global power "guardman", almost entirely relying on the father, the Soviet Union in the war of the guardian country to win the German fascists, so that Russia can stay in today's United Nations "five constants", in addition to the military legacy of the Soviet Union, so that Russia in the military level, can pull a hand with the United States.

The status of the "five permanent members" and its strong military strength have allowed Russia to remain in the club of "global powers". What Putin can do now may be to keep this only remaining glory. If the conflict between Russia and Ukraine is not over, Russia's vitality will be severely damaged after a few more years of fighting. Let alone sitting at another table, it may not be able to get to the table.

At the time the Soviet Union collapsed, the global pattern moved to the era of "a super strong", then the world shouted the multi-polar slogan, why Russia, Europe and Japan did not argue, multi-polarized into an airline. Only China continued to develop, strong rise, narrowed the gap with the United States, can have today's "G2" lead the global pattern.

Trump used the "G2" to adjust the meeting between China and the United States, and there is both a respectful side of complimenting China and a side of reluctance.The United States, of course, is not willing to stand up with China, but with the growth of China's strength, the world is destined to no longer be "a unique one".
