Imo I think the biggest thing is it would be completing the revolution in the sense that the KMT fled to Taiwan and is a holdout, that would be a huge win for national pride and legitimacy for the government. The second biggest thing would be nothaving another country with an army so close to them that is “hostile” to their interests. And then after that there would be a lot of other benefits like absorbing their industry, economic zones, military bases, etc. They would much rather have the modern KMT party win an election and vote to become a part of China, than invade, which while very unlikely is not impossible by any means in the span of decades.

Every news source has bias, Al Jazeera has over 3000 staff, over 400 journalists and access that comes along with being that massive of a news agency. Obviously they are biased towards reporting that favors the government of Qatar who funds them. Particularly if a lot of stuff is happening in the middle east and Al Jazeera has more journalists in those countries with better connections to those countries they are gonna be first to cover a lot of things in the region. They are also much less likely to use passive voice and other qualification when talking about things like Palestine in their reporting. A lot of people don’t want to read “50 Palestinians are shot” instead of “IDF battalion kills 50 Palestinians”.
