Trade deals signed at the 115th China Import and Export Fair, the nation's largest trade event held in Guangzhou, have fallen 12.64 percent year-on-year to $31.05 billion, the organizers said on Monday.

Number of overseas buyers also declined 7.23 percent to about 188,000 compared to the spring session last year, according to Liu Jianjun, the spokesman of the event.

"The sluggish performance was due to a slow recovery in traditional market and a low demand in emerging market," Liu said.
