A welcoming ceremony will be held at Government House Friday, when Mr Museveni is scheduled to meet with Thai Prime Minister Yingluck Shinawatra for bilateral talks.
Topics of discussion will include varied mutual and regional issues, especially trade, investment and technical cooperation. Ms Yingluck will host a welcoming dinner to honour the president and his delegation at the Santi Maitri Building.
During his visit, Mr Museveni and a group of leading Ugandan businesspersons will meet potential Thai investors from various areas. They will visit major Thai industry facilities to explore mutual trade and investment opportunities.
Uganda's leader has visited Thailand twice before -- in 2003 on a private visit and in 2004 to attend the 15th World AIDS Conference.
This is the first official visit of a head of state and head of the Government of Uganda since Thailand and Uganda established diplomatic relations in 1985.
The visit reflects the cordial ties existing between the two countries, as well as the importance that Thailand attaches to strengthening its relationship with African countries within the South-South cooperation framework.
It provides an excellent opportunity for Thailand and Uganda to expand cooperation in various areas, both at bilateral and multilateral levels, as well as to promote better understanding at the people-to-people level for the mutual benefit of the two countries.
Mr Museveni has been president of Uganda since 1986, having won four elections -- in 1996, 2001, 2006 and 2011.
