[citation needed] France and Siam signed a treaty on 15 July 1867, the territorial disputes of Indochinese peninsula for the expansion of French Indochina which led the Incident of Rattanakosin Era 112.

The Siamese agreed to cede Laos to France on 3 October 1893 as part of French Indochina with the Treaty of Peace and Convention in Bangkok, which was ratified on February 2, 1894.

In 1980, a minor incident involving live fire between patrol boats led Thailand to close its border with Laos.

These conflicts originated in rival claims to forest resources based on maps from the early days of the French protectorate.

[2] In 1988, Thai prime minister Chatichai Choonhavan opened the Indochina market, leading to a wave of goodwill gestures and business ventures between Laos and Thailand.

As another gesture of goodwill in 1992 the Politburo[clarification needed] removed from power military commander Army Chief of Staff General Sisavath Keobounphanh.

While Keobounphanh had dealt closely and effectively with the Thai military command in restoring neighborly relations, his party colleagues accused him of personal corruption.

The Hmong constituted approximately half of those living in the camps and tended to face lower chances of deportation, in part due to fear of reprisal and hope for national autonomy.

[2] Lao and Hmong resistance movements have persisted since 1975, but with the end of the Cold War, attempts to disrupt the LPDR and its Vietnamese military partners dwindled.

The Ministry of Foreign Affairs continued to press the Thai military command to live up to its March 1991 agreement to disarm rebels and discourage Laotian sabotage operations.

[8] Thai Prime Minister Abhisit Vejjajiva visited Laos in December 2010 as part of the 60 year anniversary of relations between the two countries.
