"The foreign ministry and its representatives in other countries are working on this issue to promote people's traveling."
As Vietnam has decided to reopens international tourism on March 15, Hang said the foreign ministry will work closely with the Ministry of Culture, Sports and Tourism to provide a set of complete measures for the reopening, including the policy for granting visas as directed by the government.
In general, people will be provided a visa in line with existing regulations such as the Law on Foreigners' Entry Into, Exit From, Transit Through, and Residence in Vietnam, she said.
Overseas Vietnamese having valid documents can also enter Vietnam under the same law.
