Vietnam is still around, and their debt-to-GDP ratio is lower than the U.S, Australia, and most of Western Europe. ¯\\\_(ツ)\_/¯

Unfortunately debt-to-GDP is a crappy stat to use. GDP in general is an outdated way of telling how a country is doing. 

I also would like to point out, Vietnam is not a communist country, more socialist-republic, with a ruling class of course.
