Beijing is soon to put in place tighter security and traffic controls for the upcoming National Day holidays, according to public security authorities.

By September 15, police forces, including the armed police, in Beijing and its six neighboring regions will be required to carry out night patrols, said a working conference of the Ministry of Public Security Tuesday.

Overhauls of safety in workplaces and key institutions will also be launched, Zhang Xinfeng, vice minister of the Public Security Ministry, said at the meeting, without giving further details

The conference also said traffic administrations in Beijing and surrounding areas would set up more checkpoints to enhance security control over vehicles from places outside the Chinese capital.

The Public Security Bureau of Beijing issued a provisional regulation earlier this month on its official website, stipulating traffic limits on incoming vehicles between September 15 to October 8.

The order bans transportation of toxic or dangerous chemicals within a certain region or time span unless they are subject to permits issued by traffic authorities.

Cargo vehicles, tractors and tricars will not be allowed to enter Beijing's sixth ring road except for the transport of daily necessities to the city and supplies for the National Day celebrations.

The regulation also reduced the period of validity of provisional permits for incoming passenger and cargo vehicles to three days from the original seven days.
