BEIJING  -- Customs officials will conduct more spot checks on Olympics-related items to ensure security for the forthcoming Games, customs head Sheng Guangzu said here on Tuesday.

To ensure a safe event, the national customs office and the six co-host cities' customs departments built a cross-city command network. Relevant customs offices have all confirmed a coordination mechanism with local police and security departments and made 622 work and emergency plans.

China has trained 24,012 people for Olympics security and carried out 369 emergency drills, and it also sent 160 customs staff to the Beijing Capital Airport to assist with security checks.
