Fast Retailing, the parent company of Uniqlo, experienced a significant decline in its shares, dropping by as much as 4.4%, which is the largest decrease in nine weeks.

This decline was a result of Chairman Tadashi Yanai expressing concerns about the demand for the company's products in China. In a recent interview with the BBC, Yanai mentioned that Uniqlo does not obtain cotton from China's Xinjiang region due to U.S. trade restrictions related to human rights issues. These remarks have raised uncertainties about the potential impact on Fast Retailing's business in China, a crucial market for the company.

The stock performance of Fast Retailing reflects investor apprehension regarding the implications of these statements on future sales and market presence in the region.
