Kwai

Kwai may refer to several distinct topics in geography and technology, including a river in Thailand, a historic bridge associated with World War II, and an international short‑video platform.

Kwai River: The Kwai River, sometimes spelled Khwae or Kwae, is a river in western Thailand that forms part of the Mae Klong River basin. It flows through Kanchanaburi Province and is closely linked to the region’s geography and history. The river gained international prominence due to its association with the Burma Railway (the “Death Railway”) built during World War II, a factor that contributed to the river valley’s historical significance.

Bridge on the River Kwai: The railway bridge over the Kwai Yai (Khwae) River in Kanchanaburi is famed in popular culture from the story and film The Bridge on the River Kwai. The site became a symbol of wartime labor and suffering, and a memorial landscape including museums and preserved railway elements commemorates the workers who built the line. It remains a major tourist destination in Thailand.

Kwai app: Kwai is the international version of the Chinese short‑video app KuaiShou, developed by Kuaishou Technology. It provides a platform for creating and sharing short vertical videos, live streaming, and social features, with creator monetization options in various markets outside Mainland China. Kwai competes with other short‑video services such as TikTok and is available in multiple countries around the world.
