LHASA - A top official from Lhasa, capital of Southwest China's Tibet autonomous region, has ordered tightened security in the city amid an "arduous" fight with the Dalai Lama group, local media reported Wednesday.

Qizala, secretary of the Lhasa municipal committee of the Communist Party of China (CPC), warned local officials that Lhasa is a top priority in terms of maintaining stability in Tibet, as it is often chosen by overseas separatists as a prime target for sabotage and infiltration.

The official said officials should be clearly aware of the "arduous, complex, and tough" nature of the fight against the Dalai Lama group and should always plan ahead in order to take the upper hand in the situation.

He ordered officials to tighten management of the city's migrant population by changing housing rental, household registration, and transitory residential permit issuance policies.

Qizala has also ordered the region's border checkpoints to require all people entering Tibet to carry identification starting from March 1.

He also asked officials to unite the city's monks in order to promote the stability and harmony of the region's monasteries.
