Jayasinghe, who won the silver medal in the women's 200m at last year's World Championships but also been at the centre of drug accusations, said she knew nothing of the latest threat to her career.

Shang Xiutang, vice-director of Chinese Athletics Centre, said yesterday the International Amateur Athletic Federation (IAAF) had not lifted a suspension imposed on Jayasinghe after she failed a random drug test in April.

The Sri Lankan athletics authorities said in August a suspension imposed after the test had been lifted. Jayasinghe qualified for next month's Bangkok Asian Games with a time of 11.28 seconds in the 100 metres at the National Championships on November 1.

Shang, who has just returned to Beijing from an IAAF secretary-general meeting, said the IAAF had received an appeal from theSri Lankan Athletics Association over Jayasinghe, China's official Xinhua News Agency reported.

The appeal will be handed over to the discipline committee on November 30 but Shang said there was little possibility the IAAF could release Jayasinghe for the Asian Games which start on December 6.

However, Jayasinghe said she had already signed the entry papers to participate in Bangkok and was confident of winning the 200 m gold.

``I don't know what this Chinese official is talking about,'' Jayasinghe said. ``I am fully cleared of any wrong doing and if the ban on me has not been lifted, then I should be the first to know.''

When Sri Lanka's sports authorities announced the suspension had been lifted by the IAAF, they said Jayasinghe had to undergo tests for banned steroids every three months.

She began training in July when a three-member panel appointed here on the request of the IAAF cleared her on a 2-1 vote.

Jayasinghe made her name at the World Championships in Athens, where she won thesilver medal with a time of 22.39 sec, becoming Sri Lanka's first medal winner.
