Shanghai's northwest Putuo District has attracted 15 foreign investment projects through the four editions of the China International Import Expo since 2018, the top official of the district said on Monday.

Nine overseas projects have also expanded their investments in the district thanks to the "spillover effect" of the CIIE, according to Jiang Dongdong, Putuo Party secretary.

During the 4th CIIE that wrapped up last week, Putuo's trade group signed deals totaling US$601 million with exhibitors, more than double than that of 2020, Jiang revealed.
