Tan Chau Garment Import Export Co plans to reduce its reliance on subcontracts from foreign sources and raise the proportion of its own-brand items to 20 per cent of total output by late this year, said Nguyen Thi Loan, the company's deputy general director. Clothing made with Tan Chau's own fabrics accounts for only 15 per cent of production, while the rest is manufactured under subcontract, she said.
