Why are our fishing boats or fishermen in China often detained?

China also has its own fishery boats, and Vietnamese or Japanese fishermen have also clashed with China fishery boats. These news have also been reported, but you just didn't pay attention. The so-called poor quality of fishermen, I think this is a joke. What does it mean to cross the border frequently? The reason for this can only be political. If you are interested, you can look at international relations. Foreign public opinion is very powerful, and their leaders should pay attention to the guidance of public opinion. With good use, you can win votes, divert domestic attention and enhance your prestige. Nationalism is the simplest and most practical weapon. America is the most typical example. When voters are used in election campaigns to incite anti-China, Sino-US relations will freeze. When they become presidents, they need China to boost their own economy, and Sino-US relations will heat up. In fact, the arrest of fishermen is directly related to the border conflict, so the so-called frequent crossing of the border is purely false. It's just that we think it's our own territory, but in the eyes of others it's their territory.
