Kwiatowski had expressed his desire to play for Vietnam earlier. He also joined Hung Thinh at some domestic competitions in 2019, dominating them all.
With the addition of Kwiatowski, Vietnamese tennis is confident of a men's gold medal at SEA Games 31, which will take place in Vietnam this year. He is also expected to help the nation compete in the second group of the Davis Cup next year.
At present, Kwiatowski is competing in the ATP 250 tournament in Singapore, where he has made it past qualifiers after two victories. His next opponent is South Korean Woo Soon-Kwon, ranked 81st by ATP. Kwiatowski is currently in 219th spot and beating a much higher ranked player would help him improve his placing.
After ATP 250, he is set to return to Vietnam and play for Hung Thinh at the national tennis championship this year.
