On 24 November 2025, with the rapid growth of outbound travel demand from Vietnam, Taiwan (China)'s leading one-stop e-commerce travel service platform, KKday, has united transportation services, tourist attractions, travel experiences, hotel accommodations, and food and restaurant SMEs from across northern, central, and southern Taiwan to establish the Taiwan Smart Tourism Alliance. The alliance jointly launched a curated tour plan, the "One-Week Round-Island Tour," and utilized diverse business models—B2C, B2B, and B2B2C—to strategically expand into the Vietnamese market.
