Nong Khai, a serene border province in northeastern Thailand, lies along the Mekong River, opposite Laos. Known for its scenic beauty and cultural tourism, Nong Khai attracts visitors for events like the Naga Fireball festival during the end of Buddhist Lent. Historically, the province has deep roots in the Lan Xang Kingdom, as evidenced by several ancient towns and inscriptions dating back to the 16th century, such as those found at Wat Chom Mani and Wat Si Mueang.

Nong Khai’s historical significance increased during the reign of King Taksin in 1779 when Thai forces brought the region under control. The town grew in importance, especially during the reign of King Rama V, who designated Nong Khai as the center for the Lao Phuan administrative region. The province has strong cultural ties with Laos, seen in the many Lan Xang-style relics like Phra That Bang Phuan and the Wat Pho Chai Buddha statues.

In 2011, Nong Khai was split to create Thailand’s newest province, Bueng Kan. Nong Khai’s geography spans narrow, fertile land that runs along the Mekong, supporting extensive agriculture, with an efficient irrigation system fed by the river. With the opening of the Thai-Lao Friendship Bridge, Nong Khai has also become a major trade and tourism gateway between Thailand and Laos, further solidifying its role as a hub for cross-cultural connection.
