Phanuwat Sukmuang has pitched for the Thai national team.
Sukmuang pitched two games in the 2014 Asian Games. Starting against Taiwan, he was rocked for 11 hits, one walk and 12 runs (10 earned) in one inning in taking the loss. He fared better in a 13-7 Thai win over Hong Kong; relieving Siraphop Nadee with two out in the 6th, he pitched 2 1/3 shutout innings, allowing three hits, before Chanatip Thongbai took over.  He also had mixed results in the 2018 East Asian Baseball Cup, giving up 6 9th-inning runs (only one earned) as Thailand blew a lead to the Philippines, with a two-run homer by Juan Lozano putting the Philippines ahead for good. In his other game, he teamed with Wissaroot Sihamat in a two-hitter over Singapore; he turned in two hitless frames to close it out. 
The right-hander got the first win in the 2018 Asian Games, relieving Adichat Wongvichit with a 12-0 lead over Laos in the 5th and a one-hitter in progress. He retired all six batters he faced: Thongvanh Her by K, Peun Silouanglath on a grounder, Syvone Yelee swinging, Bee Sengsoulin on a grounder, Gniatou Nalor looking and Soukhalom Thatsaphone with his 4th K. Thailand advanced to the main round of the Games. Against China, he relieved Sakai Phraechai with a 9-0 deficit in the 5th, two on and two outs. He allowed a run-scoring single to Shunyi Yang but retired Fujia Chu. In the 6th, he retired Chen Chen but Xiaolei Du and Chenchen Luan doubled; Wongvichit then took over and both inherited runners scored. In the game against Silver Medal winner Japan, he took over for Phraechai with a 13-0 deficit in the 4th and was hammered for 10 hits, 3 walks and 11 runs in 2 innings to close out the mercy rule defeat. He outdueled Hong Kong's Chi-Kam Kenneth Chiu for most of his third game, working four shutout innings and carrying a 4-0 lead before Ho-Yin Benny Tam hit a two-run homer in the 4th and Ho-Nam Leung doubled in a third run; Phraechai relieved and the bullpen would not hold on, costing him a potential win. In the main round of the Games, he had the 4th-highest ERA among qualifiers (19.64; Chung-Hei Leung, Gunawan Khallista and Haicheng Gong were all higher). Only Gong and Nanda Dwi Saputra allowed more hits and only Saputra allowed more runs. His four homers allowed tied Chun-Pang Yuen for the most.
