The Ban Romklao Conflict (1987-1988)
Background and Dispute origins
The Ban Romklao Conflict, also known as the Thai–Laotian Border War, was a short but intense military confrontation between Thailand and Laos that occurred from December 1987 to February 1988. The conflict centered on the disputed village of Ban Romklao, located on the border between Phitsanulok Province in Thailand and Sainyabuli Province in Laos, with both sides claiming sovereignty over the area due to ambiguities in the original French-drawn border maps from 1907.
The root of the dispute lay in unclear demarcation of the border, especially in the southern Luang Prabang Range. The French maps, which defined the boundary between Siam (Thailand) and French Indochina (Laos), often ignored the natural watershed principle, leading to overlapping territorial claims. Both Thailand and Laos also contested control over three villages in Uttaradit Province, which further heightened tensions. Minor skirmishes and clashes had occurred since 1984, but the situation escalated in late 1987 when Thai forces occupied Ban Romklao and raised the Thai flag, prompting strong protests from Laos.

Further talks were held in March, however, none led to a resolution of the border conflict. The ceasefire, continued to hold, however, even though the relations between the two countries were strained. Later on, the tensions shifted from military confrontation to cooperation between Thailand and Laos.
Current Status
Nowadays, there is no border dispute between Thailand and Laos although the tension between Thailand and Cambodia still intense. Thailand and Laos border were established some major crossing between both countries, some friendship bridges, such as ong Khai-Vientiane, Mukdahan-Savannakhet, and even various river ferries. Therefore, people and cross to both countries easily. However, Thailand has risen strictness in Visa enforcement and exemption system since November as frequent border hops via Laos are risky, with immigration now actively denying entry or extensions to those abusing the visa exemption system (often after just two runs) to prevent illegal work or long-term stays.
