China's largest trade fair saw the value of transactions drop 10.9 percent from the previous event to 194.6 billion yuan ($36.9 billion) due to lower market demand, industrial competition and trade friction, organizers said on Monday.

Liu Jianjun, spokesman for the China Import and Export Fair, widely known as the Canton Fair, said the number of overseas buyers also dropped by 6.5 percent from the previous session to 189,646.

"Overseas demand for Chinese goods, especially from the traditional market, has yet to fully recover," Liu said.

The fall session of the fair concluded on Monday in Guangzhou, the capital of Guangdong province.

"Chinese exporters should attach more importance to upgrading businesses to ensure sustainable development in the future," Liu said.
