Some people say that Buffett is buying a lot of China stocks. Is it credible?

Look at the joke told by the man downstairs first: Gates invited Buffett to visit Microsoft and had a meal. Buffett went back and bought only a small amount of Microsoft shares, but later he bought Coca-Cola shares. Buffett is buying China shares. How much did he buy?

In addition, Buffett has heard of buying Chinese stocks. Whether it is true or not, Chinese stocks have AB shares and are unlikely to buy A shares.
