With 30 days to go before the grand opening of the gala, Shanghai Party chief Yu Zhengsheng said the city can ensure the security of the 184-day event with the key being mobilization of people and careful implementation of plans.

"All the infrastructure will be completed in time; all measures on security, traffic and publicity have been taken, and residents have high expectations of the Expo - all of which show that we are ready," he said.

"I am confident that with the help of the public, we will do an excellent job on security," he added.

Security has become a paramount issue following Monday's double suicide bombings in Moscow, which killed 39. Another two suicide bombings in Russia's North Caucasus region on Wednesday killed at least 12.

Major Chinese cities have stepped up security checks at subway stations while some propose upgrading checks at bus stations.
