It is probably because it is among the top three countries with the highest crypto adoption rates. In 2023, India was on top, followed by China, the second country with the highest adoption rate with 35M crypto users. Despite this, I agree with you that there has been such news in the past as well, but country's stance about Bitcoin and cryptocurrencies never changed, at least not so far.
China and the United States are the two largest economies in the world, their economic decisions and policies will also have a direct impact and influence on the whole world and bitcoin is a part of world. Or it can be said that the world economy is in the hands of these two countries so it is not surprising that everyone is interested in anything related to them.
China is a formidable rival of the United States and as far as I know, they have never given up on their goal of taking the world number 1 position from the United States. So they will try not to fall behind the United States in any field. They may not like bitcoin but if Trump creates a race for bitcoin demand and the whole world has to follow, China cannot stay out of it.
