Every athlete who go for training overseas should undergo compulsory doping test before representing the country at international games.

Malaysian chef de mission to the Incheon Asian Games, Datuk Daniyal Balagopal Abdullah this is to avoid a repeat of what happened to wushu exponent Tai Cheau Xuen.

Tai was stripped of her gold medal after testing positive for the banned stimulant 'sibutramine' on Sept 20.

Daniyal said the Olympic Council of Malaysia (OCM) and national sports associations have to ensure that their athletes are free of banned substances.

The associations should also conduct random screening and authorise the National Science Institute (NSI) to inspect the athletes.

The OCM, NSI and the Malaysian Anti-Doping Agency (Adamas) used to conduct random doping tests on athletes and the samples sent to the National Dope Testing Laboratory in New Delhi, India.

Daniyal said he was still waiting for the Court of Arbitration for Sport's (CAS) reason for dismissing Malaysia's appeal of Tai's case.

On Tuesday, the Olympic Council of Asia (OCA) stripped Tai of her gold medal in the women's nanquan and nandao event after failing doping tests.

For the record, sepak takraw players Firdaus Abdul Ghani, Hanif Azman and Aznan Raslan were ejected from the 2002 Busan Asian Games after testing positive for morphine.
