The Long Sap border gate was established on March 1, 1990, according to the 1990 Vietnam - Laos Border Regulation Agreement. It is located in Phieng Cai hamlet, Long Sap commune, Moc Chau district, Son La province, while its Lao counterpart is in Pa Hang hamlet, Sop Bau district, Houaphanh province.
On December 22, 2020, the Vietnamese Government issued a resolution to upgrade the Long Sap border gate to an international border gate. Subsequently, on December 31 the same year, the Vietnamese Ministry of Foreign Affairs sent an official diplomatic note to the Lao side, notifying them of the decision and suggesting Laos promptly advance the Pa Hang border gate to the status. On September 16, 2024, the Lao Government approved the project.

The official urged relevant agencies and local authorities in both nations to prioritise investment in socio-economic infrastructure in border areas and border gates, including the Long Sap–Pa Hang pair. He stressed that such efforts would bolster economic, trade, investment, and tourism cooperation between Vietnam and Laos.
Phoxay Khaykhamphithoune, Deputy Minister of Foreign Affairs of Laos, regarded the inauguration as a vivid demonstration of the traditional friendship, special solidarity, and comprehensive strategic comprehensive between the two countries. He noted that the event reflects the deep mutual trust and consensus between their leaders and citizens.
The official called for continued collaboration to maintain a shared border of peace, cooperation, and friendship. Such efforts, he added, would strengthen the special Vietnam-Laos relationship, ensuring its sustainability and growth for future generations.
