Decree No. 73, released in 2012, stipulates that the number of Vietnamese students in a foreign-invested primary or secondary education establishment must not exceed10 percent of the total student body. The ratio must not be higher than 20 percent at foreign invested high schools. This has presented difficulties for foreign-owned institutions in Vietnam. Domestic investors, on the other hand, are seeing great opportunities to dominate the international education market in Vietnam – reports VietnamNet.
