The UK has launched a scheme to cut tariffs on hundreds of products from some of the world's poorest countries to try to boost trade links.
The preferential terms, which come into effect early next year, will affect products ranging from food to textiles.
Under the Developing Countries Trading Scheme, 99% of goods imported from Africa will be duty free.
Ministers say the scheme helps to fulfil the post-Brexit pledge to take back control of the country's trade policy while also reducing dependence on aid.
