China will work on a counter-terrorism law if the fight against terrorism requires it, said a senior official with the top legislature here on Sunday.

To draft a counter-terrorism law, the legislature will have to evaluate the situation, consult related agencies and conduct research, said Zang Tiewei, deputy head of the criminal law division under the Commission for Legislative Affairs of the Standing Committee of the National People's Congress, on the sidelines of the ongoing parliamentary session.

The legislature will have to follow legal procedure, Zang said.

About a week ago, a group of knife-wielding assailants indiscriminately attacked civilians at a railway station in Kunming, provincial capital of Yunnan, causing 29 deaths and injuring another 143.
