The president of China is what that will come to people's mind and not the one that is least expected. But I do not think that is going to happen. As China did not support bitcoin and cryptocurrencies generally, bitcoin still continue to increase. Which means bitcoin do not depending on China to grow.
China government gets something wrong. That bitcoin may let their currency, yuan to lose value but that is not true.
If China government decided to unban bitcoin then there's a possibility that it may result in bullish in my opinion although as you have said, bitcoin did not depend on China to grow which means it didn't depends on any country to grow but it is possible that a country can help it grow. I think this is a bit similar to what will happen to bitcoin if there's no more miner from china due to the ban the use and mining of bitcoin in China.
