Chinese legislators are proposing an amendment that would make it a crime for people who force others to wear clothes or symbols in public associated with terrorism and extremism, which analysts said would take the anti-terrorism campaign to a different level.

Those found guilty could be jailed for up to three years, according to a draft submitted to China's top legislature - the Standing Committee of the National People's Congress - during the bimonthly session that started Monday.

Analysts said the amendment could further strengthen the nation's efforts to combat terrorism, after the nation witnessed several terror attacks outside the Xinjiang Uyghur Autonomous Region and other places, including Beijing.

"The amendment could prevent terrorist activities from spreading across China. It shows the nation's zero-tolerance toward any action related to terrorism or extremism," Li Wei, an anti-terrorism expert at the China Institutes of Contemporary International Relations, told the Global Times Monday.

Li said that the symbol of the East Turkestan Islamic Movement has appeared in previous terror attacks in China in the form of a black flag with a crescent.

Xinjiang imposed a ban on wearing full-face veils in public in Urumqi in December. Local regulations also banned people from forcing others to wear clothes or symbols associated with religious extremism, media reported.

"But it is not clear what extremist clothing look like. Judicial interpretations could answer all questions until this draft amendment is passed," said Wang Guoxiang, an expert at the Beijing Academy of Social Sciences.

Reports said the death rate of active police officers is 5.4 times higher in Xinjiang than the rest of the country. Last year saw the deaths of 230 government officials, a number way above China's average. A third of police killed in the country were from Xinjiang.

The top legislature is also considering tougher sentences for assaults on active police officers.
