"Chinese garment exporters have lost their cost advantage in recent years," she said. "If we turn down customers because of the price, they will turn to factories in Southeast Asian countries such as Cambodia and Vietnam. But if we accept the price cuts, we undertake the risk of a revaluation of the yuan," she added.

In a move to cut costs and increase competitiveness, Yiwu Qijia Garment Co has started importing products from factories in other Southeast Asian countries and selling them to its foreign clients.

"Imported garments account for about 30 percent of our total sales," Wu said. "Devaluation of the yuan will definitely increase our costs in terms of imported products."

Wu's company, which is based in the eastern coastal province of Zhejiang, exports women's clothing to overseas markets that include Brazil, Japan, Europe and Russia.

"It is true that the depreciation of yuan has helped us to be more competitive in global markets, but the benefits are actually not as great as people might imagine," she said. "Our company exports garments worth about 30 million yuan a year.

"The currency change might bring only 150,000 yuan to 180,000 yuan more, and no one knows which way the yuan will go in the future," she added.

Shao Longhe, general manager of Welfull Group in Zhejiang province, shares Wu's views when it comes to China's currency fluctuations. He is not convinced the depreciation in the yuan will boost exports.

As the general manager of a State-run import and export company, Shao has 20 years experience in the business.

Welfull Group exports annually 200 million yuan of goods, including garments, textile products, bags and furniture. Most of the contracts he signed with overseas clients were fixed at the old currency rates.

"What is confusing us now is that we are about to renew our contracts for next year," Shao said. "The problem is deciding a rate and price."

While the decision to revalue the yuan has boosted confidence among Chinese exporters in labor-intensive industries, it might not turnaround slowing exports.

"Devaluation of the yuan alone cannot bring Chinese exports back to the peak periods before the financial crisis in the West in 2008, because overseas demand is weak," he added. "Most exporters in China rely on quantity to make money and that can not happen if demand keeps dropping."
