Some US$837 million in foreign trade deals were signed at the China-Northeast Asia Expo which closed Tuesday in Changchun, capital of Northeast China's Jilin province.
The five-day event drew more than 100,000 attendees from over 110 countries and regions, said Li Jinxiu, director of the expo's executive committee.
Domestic trade deals worth 2.45 billion yuan (US$375 million) were signed during the expo, said Li, also vice governor of Jilin.
Some 235 investment projects, with combined investment totalling 224.3 billion yuan, were also signed at the annual event.
This year's expo attracted more international attention, as it highlighted topics such as intelligent manufacturing and the Belt and Road Initiative, according to Li.
The expo was jointly organized by the Ministry of Commerce, the National Development and Reform Commission, China Council for the Promotion of International Trade, and Jilin provincial government.
