Despite the current slowdown in world demand, Chinese exporters have shown a great interest in participating in the upcoming China Import and Export Fair, a gauge of the state of China's foreign trade.

"More Chinese companies are hoping to attract foreign buyers by showing their products at the fair," Liu Jianjun, spokesman for the fair, said on Tuesday.

The twice-a-year fair, also widely known as the Canton Fair, will open on Sunday in Guangzhou, capital of Guangdong province.
