Though capable of high level singles (he won Japan's "World Invitational" tourney in 1964 and ousted Erland Kops in the first round of the 1966 All Englands), Yee Khan was primarily a doubles player who won numerous major international titles in partnership with Ng Boon Bee. Powerfully built and substantially bigger than most Asian players of his day, he was reputed to be the hardest smasher in the game. He won the coveted All-England men's doubles title with Boon Bee consecutively in 1965 and 1966. In 1967 he was a member of Malaysia's world champion Thomas Cup (men's international) team. Plagued by back problems he retired from badminton competition in 1969 but soon became one of Malaysia's leading golfers. He was elected to the World Badminton Hall of Fame in 1998.
