With which countries does China still have territorial disputes?

At present, the borders with Japan, India, Vietnam, the Philippines, Malaysia and several countries in Central Asia have not been demarcated. According to Taiwan Province Province, then Russia, Myanmar, Pakistan and Mongolia will be added as a whole.

So up to now, the land area of China is about 9.6 million, which is not clear. With a land area of 9.63 million, the United States ranks third in the world, and China ranks third in the world. However, when the United States asked about the land area of China, China was speechless and didn't dare to say it himself.
