There has been some confusion in Thailand and on discussion forums about Mr Obama's official function. As in any republic, he is both the head of state and the head of government of the United States. He will meet the king as US head of state, but then talk to Prime Minister Yingluck as the US head of government.
Police, soldiers and security officers have been ordered to tighten up security for the president during his stay in Thailand.
All venues Mr Obama will visit, including Siriraj Hospital and Government House, and the streets he will travel through will be under close watch, police chief Kamronwit Thoopkrachang said.
US security officers will also tail the president by land, as well as by air with a helicopter.
The Royal Thai Air Force, together with its Security Force Command and police officers, will work with US officers to maintain security at Don Mueang airport where Air Force One will land, Royal Thai Air Force spokesman Monthon Satchukon said.
