Prime Minister Yingluck Shinawatra's security detail also was planning and rehearsing for a reception for the US president.

The United States is interested in establishing a humanitarian and disaster relief force at U-Tapao, a naval and air force complex on the eastern seaboard built by the US military during the Vietnam War.

US officials have announced plans to focus more on the Asia Pacific region in military, cultural and development areas.
