Kou Voravong
But the country was immersed in a civil war, itself within the context of the Cold War. In 1963, when his uncle the General Sarit Thanarat died, he lost Thailand's Government support, while on the other side, the United States opted for direct military intervention policy. At the end of January 1965, after several "disobediences" to the American military advisory, and following a coup against his government, whose instigator was General Kouprasith Abhay, Phoumi Nosavan was forced to go into exile in Thailand with his followers and relatives. The statue of Kou Voravong had not been erected and still waiting in the reserve of Fine Arts Department in Bangkok during nearly 30 years.
