The textile and clothing industry, one of the engines China used to fuel its own economic expansion in the 1980s, has been particularly hard hit in Africa. For decades, African countries exported large quantities of clothes and textiles to developed countries under a trade agreement intended to protect European and American markets from competition from China and others, while encouraging exports from the world’s poorest nations. But the trade provision, the Agreement on Textiles and Clothing, expired in January 2005, putting these countries in direct export competition with China.

Africa found itself once again on the losing end of globalization. If copper is Zambia’s bread and butter, manufacturing should have been its main meal — just as many economies across the globe have progressed from producers of raw materials to low-tech manufacturing and beyond, a well-trod path to development.

Ms. Zimba, 40, a quality-control worker at the plant here who asked to be identified only by her common last name because she feared losing her termination benefits, first got a job at the factory in 1989, after moving to Kabwe from the depressed eastern region of the country with her brother.

She earned a little less than $100 a month, as well as free health care and a pension, and a little three-room house in the workers’ compound. But since she lost her job, her family’s standard of living has plummeted. The water was turned off, and Ms. Zimba does not know where she will come up with next semester’s tuition for her 20-year-old daughter’s trade school.

“We will see what God brings me,” Ms. Zimba said.

For Ms. Zimba, the transition from salaried work to selling goods for pocket change in the market is a devastating setback to a grim fate she thought she had escaped — her mother was widowed when Ms. Zimba was 15 and reduced to selling in the market as well.

“I am right back where I started,” Ms. Zimba said.

As for the Chinese, she bitterly refers to them as “briefcase investors.”
