Most Asian nations are pro-Chinese. That's a fact you'll have to live with.
Apart from Pakistan, I don't find any nation pro-Chinese. Perhaps, North Korea, but do you even count that as a Nation?
Japan- very anti-China
Korea- neutral China, still allied with US, and its anti-China alliance
Mongolia- anti-China, but since it is surrounded and can't do much, it is bound to be neutral-China
Taiwan- very anti-China, though not a nation, I write about it here, because it is a defacto state, and also supported by US, which can use it for all kinds of things.
Vietnam- Very anti-China
Philippines- Very anti-China
Malaysia- neutral to weary about China
Singapore- neutral to weary about China
Indonesia - neutral China, but the civil society of Indonesia is weary China.
Thailand- neutral to pro China, population also, neutral to pro China, Chinese perceptions soiled by bad behavior of Chinese tourists
Myanmar- neutral to weary China, population weary China, they seriously are made to believe by the junta that all the problems in border areas has been fostered by Chinese.
India- weary to anti China, civil society and security establishment- very anti China
Australia- weary China
Most Asian nations are pro-Chinese. That's a fact you'll have to live with. Singapore and Malaysia are not calling for more US action, not broadly. The fact is, Singapore and Malaysia will both pick China any day of the year if forced to choose sides.
They mean "spoiled" by Chinese standards. The typical overseas Indian or Western brat is considered insufferable to all Chinese societies.
Manners please. You could have delivered your message without using "brat."
