Regional income convergence in Indochina 1970–2015?

Real incomes have been increasing relatively fast in the Indochina region but there are still large differences in income levels between the six member countries. Based on the various sources of national accounts data, it seems that the low-income countries have experienced the highest growth rates. Time series tests of convergence, in this case catching-up to the relatively high-income level in Malaysia, confirm that Cambodia, Myanmar, Thailand and Vietnam have narrowed the income gap during the last two decades.
