Africa-China textile tensions erupt

Trade between Africa and China is now thought to be worth around $160bn every year.
However, as the relationship between the two develops beyond raw materials, it is bringing tensions as well as benefits.
One of the flashpoints has been cheap Chinese textiles, which some African companies say are putting them out of business.
Earlier this week Nigeria arrested dozens of Chinese textile traders, but have now released them.
