I think only Vietnam will break through. It has a decently hardworking workforce, a government that can force through changes because of authoritarianism. Also it benefits from proximity to China, relative lack of secessionist threats. It has a very strong renewable energy policy backed by feed in tariffs and is one of the world hotspots for offshore wind projects - government is very enthusiastic about it. With 100 million people and decent governmental policy, it should be a middle power by 2050.
I think so too
Vietnam's education scores are also very high
After all, Vietnam was part of the Confucian Sinosphere for millennia
