I'll just say, having lived in Vietnam for quite some time, it certainly is a much better country than China, but describing it as "mixed" and "partially socialist" understates its issues. Corruption is rampant and open, and is the way of things in both the private and public sectors.

As just one example, the Saigon Metro project began construction not long before I stopped living there in 2012, and was scheduled to finish in 2018. Rampant corruption with that project has meant multiple times it's just stalled with seemingly no progress made for years, and the Japanese construction company hired to do some of the work threatened to pull out over cost overruns caused by the corruption. It's a lovely country in so many ways, and its government is so much better than those that tankies usually love to praise in terms of the degrees of gross authoritarian bs, but it's got a long it could improve in many regards.
