Born in Nepal in 1985,[2] Manoj Katuwal first played for Nepal at Under-17 level when he played in the ACC Under-17 Asia Cup in Bangladesh in 2001. He played for Nepal Under-19s at the Under-19 World Cup in New Zealand the subsequent year and made his début for the senior team later that year in the ACC Trophy in Singapore.[4]
His appearances for the Nepalese team became less frequent at this point in his career. He played an ACC Fast Track Countries Tournament match against Malaysia in October 2005,[4] before playing a match against Namibia in Windhoek to decide the final team in the 2006 ICC Intercontinental Cup. Nepal had to win the match outright to qualify for the main tournament, but the match ended in a draw.[6] He most recently played for his country in the ACC Premier League in 2006, when he played against the UAE.[4]
