In June 2015 both Sokpheng and his brother Sokngon were signed by Phnom Penh Crown to play in the 2015 Cambodian League.
Ironically Phnom Penh Crown's first game of the season was against the Keo brothers' former team, Boeung Ket Angkor.
[7] He was released by PKNP in May 2018, but despite rumors he rejoined Phnom Penh Crown,[8] Sokpheng joined another C-League team, Visakha FC in June 2018.
Soon after he was called up to the senior side to take part in 2018 World Cup qualification,[10] where he started in a 1–0 home defeat to Afghanistan.
[citation needed] He was born from a Chinese-Vietnamese family, lived in Vietnam until 14 years old and was a big fan of the Vietnamese footballer Lê Công Vinh.
