China had at least some respect for the Trump administration. They realized, after testing him, that President Trump would not let them get away scot-free with their actions, but would call them out and impose retaliatory measures if necessary.
They haven't taken long to demonstrate decisively that they don't have the same respect for President Biden. Within days of his taking office, they renewed their saber-rattling over Taiwan. They flew many more incursions than usual into Taiwan's air defense zone, and their pilots exercised an attack on a US naval force in the area. I expect military action there within a few months, if events continue along their present course.
All it took was President Trump leaving office and the Chinese moved.
To be fair about it, China has been dumping lots of money into Myanmar. They dropped US$ 100 billion last summer in a country with a GNP of $US 76 billion, as part of the Belt Road Project. Not all of it was official national money. A lot of the money arrived by way of cut-outs, and some of it was “soft money” but China bought the coup.
The military coup is said to be anti-Chinese, but it’s not. Just the opposite is true.

In so many words, China is daring the Biden administration to oppose them. As each successive challenge doesn't generate an appropriate response, they'll grow bolder and more aggressive. It won't take long for China to decide that the USA is so focused on its internal divisions and politically correct policies that it won't respond to foreign threats. If they become sure of that, then Taiwan is toast - and that's just the start.
I have no confidence whatsoever that the Biden administration is up to the challenge. Japan, India and Australia should be getting nervous. Very nervous. If they have any sense, they're probably already thinking about the fate of another abandoned US ally in the region . . . namely, South Vietnam.
