BEIJING, June 1 (Xinhua) -- Thailand secured two championships on Sunday at the Singapore Badminton Open, with Kunlavut Vitidsarn winning the men's singles crown and the mixed doubles pair of Dechapol Puavaranukroh and Supissara Paewsampran also triumphing.

Second-seeded Kunlavut dominated the men's singles final, defeating China's Lu Guangzu 21-6, 21-10 in just 37 minutes. The victory marked Kunlavut's fourth title of the season and is set to propel him to the world No. 1 ranking in the men's singles when the Badminton World Federation (BWF) releases its latest standings next week. He will also become the first men's singles player born after 2000 to achieve the top ranking.

Earlier, Thai mixed doubles stars Puavaranukroh and Paewsampran captured their title by defeating Tang Chun Man and Tse Ying Suet of Hong Kong, China, 2-0 in the final.

China's Chen Yufei claimed the women's singles title, defeating compatriot Wang Zhiyi in straight sets for her fourth championship of the season. Notably, Chen ended the 27-match winning streak of reigning Olympic gold medalist An Se-young of South Korea in the quarterfinals. Since returning to competition in February following a three-month study break in Australia, Chen has regained her form and extended her own winning streak to 22 matches.

In doubles action, South Korean pairs secured one gold and one silver medal. Kim Hye-jeong and Kong Hee-yong won the women's doubles title by defeating Japan's Rin Iwanaga and Kie Nakanishi 21-16, 21-14. However, Malaysia's Aaron Chia and Soh Wooi Yik beat Kim Won-ho and Seo Seung-jae 15-21, 21-18, 21-19. ■
