More than 200 projects are set to be signed during the ongoing Western China International Fair for Investment and Trade (WCIFIT), held from Thursday to Sunday in Chongqing.

According to the organizing committee, 124 were finalized at the opening ceremony on Thursday, with an additional 88 to be signed by the city's districts and counties later.
