Not to mention, China has made any invasion impossible, or at least very difficult. China has an area of 9.6 million square kilometers. About half of the countries are densely populated, or 4.8 million square kilometers. In other words, Japan and Taiwan, China of China can allocate only 0.47 people per square kilometer. In World War II, Japan deployed 4.5 million troops and another 1.5 million Huangxie troops, which only accounted for about 2 million of China's existing land. Even then, the large-scale guerrilla war also caused great damage to the Japanese army.

If Japan seriously evaluates its military capabilities, it may lead China in some economic and scientific fields, which is enough to make China sweat a little, but alliance with Taiwan, China is still not enough to give it any opportunity to invade. Seventy years ago, the United Nations military led by the United States failed, let alone the two small areas.

Once the invasion begins, the military infrastructure of Japan and Taiwan, China will be destroyed by Chinese missiles. I am not talking about nuclear missiles, but thousands of conventional cruise/short range/medium range missiles owned by China. Most of them are installed on offshore or mobile platforms, so it is almost impossible to take them out before launching.

The Chinese People's Liberation Army also has a very advanced air defense system, which benefits from decades of technical exchanges and internal development efforts of Russia in recent years. If Japan and Taiwan, China want to succeed in any invasion scenario, it is very important to gain air superiority at the beginning of the war, and this is impossible. For example, it is suggested that China's HQ-9 SAM is equipped with 305A AESA radar, which can track and shoot down stealth (but not completely stealth) targets, such as the F-35, which is just the most advanced fighter that Japan has in the foreseeable future.
