BEIJING -- Chinese soybean farmers have urged the government to come to their rescue as they are grappling with an influx of cheaper, genetically-modified soybeans from overseas.

They expressed worries that over-reliance on soybean imports -- as high as 80 percent -- could put the country's cooking oil and animal feed industries, which use soybeans as major material, in despair.

"The Chinese soybean industry suffering from shrinking planting areas is at the crossroads of life and death," said Sun Bin, a farmer from northeastern province of Heilongjiang.

China has become increasingly dependent on soybean imports and foreign capital is dominating the Chinese soybean market, said Sun, also one of nearly 3,000 lawmakers who are in Beijing for the annual session of the National People's Congress.

Heilongjiang accounts for about one-third of China's annual soybean output. The province's soybean planting area, however, slumped significantly from 4.7 million hectares in 2009 to 2.53 million hectares in 2012.

During the period, farmers in the province planted more corn, which has a higher yield and is more profitable.

"When farmers can earn 4,000 yuan ($635) more from a hectare of corn than from soybeans, who is willing to plant soybeans?" said Qu Fa, another farmer from Heilongjiang.

Aggravating the woes of soybean farmers, soybean processing plants were reluctant to buy domestic soybeans.

At present, imported soybeans sell at 4,400 yuan per ton, while domestic soybeans are priced at 4,600 yuan per ton, said Wang Xiaoyu, deputy secretary-general of the Heilongjiang Soybean Association.

Soybean farmers in the province have been caught between the hammer and the anvil, Wang said.

Foreign Hands

Cheap imported soybeans have led China to become a net importer of soybeans.

In the mid-1990s, China opened up its soybean market to import more soybeans to satisfy greater domestic demand for cooking oil.
