An external conflict is brewing. Most people think it means a war with conventional weapons, but that is just one way of waging war. The United States and China are waging a trade war, a technology war, a geopolitical war, and a capital war. The military conflict is being waged between Russia and Ukraine. In reality, both the United States and China are involved. Other parties include Europe, Canada, North Korea, and Iran. All of the above are indirectly involved. Neither side can let its ally lose the war.
The rise of China threatens the leadership of the United States. According to Graham Allison, in the last 500 years, there have been 16 similar situations, and 12 of them have led to military conflict. A military conflict between the United States and China is likely in my opinion. I would put the probability at 60%. One reason for this is that the United States sees China as the greatest threat. Military conflict before war is fought on other fronts.
A trade war is underway. It is being waged mainly through tariffs, corporate subsidies and market regulation. Industrial espionage is also widespread. It works both ways, although the United States suffers more from it. According to the United States, the decline caused by China is more than $150 billion per year. The United States and China have both imposed import tariffs on each other. China is preventing US companies from entering its country. This is also true on a smaller scale in the other direction. Export subsidies for Chinese companies are common.
Both could engage in a full-scale trade war. China's biggest weapon is banning the export of rare earth metals to the United States. It owns the majority of them. The United States has banned the export of the most advanced semiconductors to China. It could also affect oil exports to China from the Persian Gulf states. The same applies to the export of metals from Australia to China. The United States has the greatest weapon of economic mass destruction at its disposal: excluding China from the SWIFT system. This would quickly destroy the Chinese economy. At the same time, all the capital of US companies in China would be lost. This weapon would probably only be activated if a direct military conflict between the countries begins. This conflict would take place either near China's east coast or in Europe with other countries participating in the war. Both countries are too challenging to conquer, so any possible war would be fought outside their borders.
The US and China are ahead of other countries in technological development. In semiconductors, they are second only to Taiwan. The most advanced semiconductors cannot be manufactured without certain raw materials that can only be obtained from the US and Europe, so Taiwan is dependent on them. On the other hand, China cannot prevent their manufacture. The US and China have strengths and weaknesses. The US is clearly number one in military technology. In addition, it is number one in the exploitation of artificial intelligence, at least commercially. It is also less dependent on technologies developed by other countries. The situation may be changing in China's favor. China is ahead in radio networks, mobile payments, and it knows more about its citizens than the US. The majority of the largest technology companies are in the United States.
Although the United States is now ahead, China has a numerical advantage, as it has about 8 times the number of technology students. China could overtake the United States early next decade. The United States has responded to the Chinese threat by banning the use of Chinese companies such as Huawei's technologies and is pressuring others to do the same. China has forced foreign companies to hand over their technologies if they have wanted to enter the country. The country also engages in large-scale cyber espionage. It would be naive to think that the United States would not do the same. China's drive to become self-sufficient in high technology is progressing well, except in the case of semiconductors. The United States is in a hurry to accelerate its technological development.
Geopolitical warfare is taking place around the world, but it is fiercer near China's east coast. A war is being waged in the East and South China Seas, where the fate of Taiwan will be decided. China has acted in violation of international law by building artificial islands, for example, in the South China Sea. It claims this area as its own, extending all the way to the coast of Malaysia. The major parties in the region are China, North Korea, possibly Russia, and their counterparts, including Taiwan, Japan, South Korea, Vietnam, the Philippines, and the United States. China believes that Taiwan is part of it. This is the most sensitive point of contention and could lead to a military conflict on the eastern side of China. China wants to avoid this until it is certain of its victory.
China's influence around the world is growing. It is leveraging its economy by gaining access to natural resources on other continents. Its position in Africa in particular has strengthened. It is not only exploiting the continent but also building roads and other infrastructure on it. It is a better partner for many African countries than the West. Elsewhere in Asia, its partners include at least Iran and Pakistan. Its opponents include at least Australia and other US allies.
The capital war is being waged, among other things, over currencies. China controls the Yuan's exchange rate against the dollar. China's biggest risk is capital controls. It mostly uses the dollar in its trade. It is trying to reduce its dependence on the dollar and is increasingly using the euro. This is evident, for example, in trade between China and Russia. The United States could stop using the Chinese dollar. The result would be economic chaos in China. This could destroy confidence in the United States in other countries if they consider the actions to be excessive.
The US dollar is the largest reserve currency. It has more influence over other countries. It gets cheap loans and its economy cannot be destroyed by other countries for a long time. It can itself destroy confidence in the dollar by printing too much money. China could destabilize the United States by seizing the assets of US companies there and selling the US bonds it owns. Their share is only a few percent, so the latter action would not have a major impact. The loss of a reserve currency is not a current concern for the United States. Later, the situation may be different. Changing the reserve currency requires decades of changes to the global financial system, so China is not able to create one for itself. Changing the reserve currency to some other smaller reserve currency that functions in the current system, such as the euro, is a likely option in the short to medium term. The likely moment for this change is only after a military conflict.
The form of a military conflict is an interesting question. I myself do not have enough expertise to say anything significant. Likely causes include Taiwan or a brief and accidental clash near China's east coast. A land war between NATO and a Chinese-led coalition is also possible. This would be used in Europe. Both the United States and China are far from a possible landing. Naval and air warfare in addition to a land war in Europe is possible.
A Chinese landing on Taiwan is not an impossible idea, but this will only happen if the United States does not protect Taiwan. The Chinese believe that the latter belongs to them, so they are in favor of a landing. The Chinese people could therefore accept this, even if there is no certainty of victory. I cannot assess the probability of a landing or its success. I also do not know anything about the timing. I do not know whether the United States will defend Taiwan during an attack. The sea area between China and Taiwan is important to the global economy. If China were to take control of it, it would significantly weaken the world economy and the economic interests of the United States. Therefore, the United States has a high threshold for leaving Taiwan undefended if China attacks it.
The likelihood of the aforementioned conflict is reduced by the fact that China needs to wait for an internal conflict in the United States before attacking Taiwan. The country is deeply divided. China's problem is the economy. It is suffering from a bursting real estate bubble and the economy is certainly not on as strong a footing as the rest of the world believes. In addition, Xi is forced to focus on internal power struggles, which reduces his ability to attack Taiwan. It is possible that this potential attack is one of the reasons for Xi's problems at home. China is turning inward and closing itself off from international actors.
