The warships, UMS 561 and UMS 562, will be in Phuket port for three days, between Feb 20-23. They will be welcomed by officers from the 3rd Naval Area Command.
It will be the first visit by Myanmar warships to Thailand, the source said.
"The visit is a sign of good relations between the Thai and Myanmar navies and shows Myanmar is now more open. There will be talks about military relations, possibly about a joint marine patrol for the first time," said the source.
The source said the navy commander of Myanmar will make a separate visit to Thailand. He will make a courtesy call on navy commander-in-chief Adm Surasak Roonruangwong in Bangkok.
