Burma's President Thein Sein arrived in Thailand Sunday for a three-day visit, after postponing the trip twice.
The Burmese leader will meet with Thai Prime Minister Yingluck Shinawatra on Monday. The two are likely to discuss development and investment in Burma and the status of hundreds of thousands of ethnic Rohinghya refugees who fled ethnic violence in Burma.
The two leaders will also witness the signing of a memorandum of understanding on development projects in Burma.
Thailand, along with China and other regional nations, became a key trading partner with Burma during its years of isolation under military rule.
