Wong then participated in the Asian Games hosted in Hangzhou, first beating then-World No. 98 Wu Yibing in the Round of 16 after saving 5 match points, making him become the first ever player from Hong Kong to beat a top 100 player. However, he lost to South Korean player Hong Seong-chan in the quarter finals 6–4, 4–6, 3–6.
