On March 11, 2017, he successfully defended his WBO International and WBC Asian Boxing Council titles and claimed the WBO Asia-Pacific title against Hirofumi Mukai. Tso battered Mukai and dropped him twice before finishing him with a left to the body in the 8th round. With the win, Tso improved his record to 21-0. In October 2017, Tso faced former WBA world champion Kohei Kono. Tso had sought to fight Kono while the latter a world champion, but was unable to draw him into the ring. After six rounds, Tso was unable to continue due to swelling around his eye. Nevertheless, Tso remained unbeaten by winning a technical decision.
