Lim represented four countries at darts; Singapore was not affiliated with the sport's governing body, the World Darts Federation (WDF), so Lim played briefly for Papua New Guinea, but settled in California and represented the United States in international competition, before also playing for his native country when they became a WDF playing nation. Lim has also represented Singapore at the PDC World Cup of Darts, and in the 2017 PDC World Cup of Darts, he and his teammate Harith Lim, reached the quarter-finals, defeating the top seeds Scotland (Gary Anderson and Peter Wright) in the first round. However, in the 2019 WDF World Cup he represented Hong Kong.
