America’s image is mostly positive among the Asian nations polled. Particularly large majorities see the U.S. favorably in the Philippines (92%), South Korea (84%) and Vietnam (77%).
It's from 2015 but more recent polls have found similar data IIRC

79% of people polled in Vietnam chose the US in the "Preferred alignment choice in U.S.-China rivalry" which is a different metric obviously but still points towards the same idea
Edit: According to Luna Oi, Pew Research Center is a neoliberal think tank that cannot be trusted on anything about Vietnam

For a lot of really stupid reasons. The US didn't execute enough traitors, these traitors wrote lots of books glamorizing their war exploits, entire organizations sprang up to spread the propaganda for decades on...
Surprisingly not even the traitors themselves. A lot of them thought they were utter disgraces for failing such as Robert E Lee, and wanted to fade away into obscurity. But then their children necromancied their corpses to lend legitimacy to furthering Jim Crow and whitewashing the south as a “Hopeless Cause” movement.
