China dominates the global bird's nest market, importing 90% of the world's production, primarily from Indonesia and recently seeking to import from Vietnam. Vietnamese bird's nest is highly valued for its quality, with Vietnam harvesting about 120 tons annually, worth around 450 million USD. The unique quality is attributed to the natural conditions and the traditional, handmade production process. Bird's nest mining is recognized as a national intangible cultural heritage in Vietnam and is a significant economic activity in Hoi An city.
