Textile is China largest export and Xinjiang cotton made up 80% of China cotton production.
Textiles have not been China's top export for a while. In 2019,
were:
1. Electrical machinery, equipment: US$671 billion (26.9% of total exports)
2. Machinery including computers: $417 billion (16.7%)
3. Furniture, bedding, lighting, signs, prefab buildings: $99.5 billion (4%)
4. Plastics, plastic articles: $84.4 billion (3.4%)
5. Vehicles: $74.4 billion (3%)
6. Optical, technical, medical apparatus: $73 billion (2.9%)
7. Knit or crochet clothing, accessories: $71.4 billion (2.9%)
8. Articles of iron or steel: $69.6 billion (2.8%)
9. Clothing, accessories (not knit or crochet): $66.8 billion (2.7%)
10. Toys, games: $62.8 billion (2.5%)
Textiles are barely in the top 10 these days: #7 and #9 together add up to less than 6% of China's total exports. Machinery, including computers, are now over 40% (#1 plus #2).
Maybe textiles are Xinjiang's top export.
maybe China should learn that and sanctioning US company one at a time.
I think the unofficial boycotting of H&M, Nike, et cetera by Chinese citizens will be good enough.
