"We must also watch out for the European Union, a key player in China's exports. The EU's debt woes will last for a long time and the biggest concern now is its unemployment and looming fiscal trouble in Italy. Sluggish demand in the EU will further drive down turnover at the Canton Fair (China's largest biannual trade fair and a barometer of its exports) after a 9.3 percent drop at the autumn event," said Wei, a former vice-minister of commerce.

Yao Jingyuan, a researcher at the Counselors' Office of the State Council, blamed weak exports in 2012 for China's slow economic growth, which expanded 7.8 percent year-on-year, the slowest pace since 1999.

Yao added: "But China's high-tech exports retained quite high growth in 2012, suggesting that the current export growth model and structure are not sustainable.

"Amid rising costs at home and fierce competition from neighboring countries with lower costs, we are now at an urgent moment to transform exports and take the downward pressure in export growth as the motivation for restructuring."

Chen Zhihan, general manager of Fujian Jiamei Group, a leading maker of ceramic artware, said: "It's not very difficult for us to get orders this year, but it's hard to beat rising costs. The exchange rate fluctuation in 2012 eroded about 10 percent of our profit while our labor advantage has disappeared and raw materials are cheaper in some overseas markets."

Guo Ruolai, assistant to the general manager of Dahuachem International Economic & Trade Co Ltd, said that its focus this year is ensuring that customers in countries with debt woes are able to pay up.

Li Demin, general manager of Dongning Huaxin Group in Heilongjiang province, said: "We expect our trade value to rise to $250 million or $300 million this year from $200 million in 2012, mainly driven by our transformation from mechanical and electrical exports to Russia to agricultural investment, which in return boosts machine exports."

Wei Jianguo added: "Training of migrant workers, or semi-skilled workers, the main source of labor at Chinese exporters, must be enhanced for the country to retain its position as the world's factory and its leading exporter.

"In addition, more efforts should be given to trade in services in order to improve the trade growth model. About 3 trillion yuan ($481.9 billion) in service trade will be shifted to China from overseas markets in the next three to five years."
