Northwest China's Xinjiang Uyghur Autonomous Region has over 20,000 mosques, 10 times as many as it had more than three decades ago, spokesman for the annual session of China's top political advisory body said Monday.

Figures proved China's commitment to respecting religious freedom of Muslims, Lyu Xinhua, spokesman for the annual session of the Chinese People's Political Consultative Conference (CPPCC) National Committee, told a press conference ahead of the annual session.

He also mentioned the number of Islamic religious practitioners in Xinjiang rose to 28,000 from 3,000 more than three decades ago.

Since 2001, the Xinjiang regional government has sent about 4,000 people to Egypt and Pakistan to pursue their studies at Islamic institutions, Lyu said.

Over 1 million copies of religious classics, books and magazines in Uygur and other languages have been published in Xinjiang, the spokesman said.

This year marks the 60th anniversary of the establishment of the Xinjiang Uygur Autonomous Region, which saw leapfrog economic and social development in the past decades.

The region with a vast land, however, was sometimes disturbed by law-breaking extremist activities.

The annual session of the CPPCC National Committee is scheduled to open Tuesday.
