Security will be stepped up at the fourth China-Eurasia Expo, which will be held in Urumqi, capital of the Xinjiang Uygur autonomous region, said an official of the Xinjiang Public Security Department on Thursday.

The fourth China-Eurasia Expo will be held from Sept 1 to Sept 6. Forty-four foreign minister-level guests will attend the expo, according to the organizing committee.

China launched a one-year nationwide campaign against terrorism in May, with Xinjiang as the campaign's focus, after a series of violent and deadly attacks by terrorists and religious extremists from the region.
