Is $1,000 usd a good salary in Vietnam?

I'm curious to know if a salary of $1,000 USD is considered good in Vietnam. Given the cost of living and average wages in the country, how does this figure stack up against the norm? Is it enough to live comfortably or is it more of a struggle? And what about savings? Could someone on this salary expect to put away money for the future? It's always interesting to get a sense of how income levels compare across different countries and cultures.
