Shopping agents feel the currency pinch

As the continued depreciation of the yuan excites China's exporters, the weaker currency is putting pressure on a group of importers - overseas shopping agents and cross-border e-commerce sites.

Tasked with seeking out popular foreign products for mainland consumers, they have been feeling the pain since August when the yuan started heading south.

"It declined too fast and too much. It's hurting my business," said Wu Yao, a San Francisco-based shopping agent, adding that consumers are becoming reluctant to buy her products which now cost more.
