>>510998814The value of ethane export controls as leverage is arguably overblown. Only about 8-10% of China's ethylene output is from ethane feedstock, and those of China's crackers that run on ethane are flexible and can use other feedstocks just as well. The alternatives are more expensive than ethane, but Chinese ethylene crackers don't have to shut down if they can't get ethane.
Meanwhile, there's not really nowhere else ready to absorb all that American ethane
US dominates export of ethane because they are the only ones who have invested heavily in ethane export infrastructure, but the US is only responsible for about 50% of global ethane production, which suggests export controls wouldn't be effective in the long term

I think export controls on other things such as LEAP turbofans was a far greater concern for Xi
