The European Union is preparing to open a new front in efforts to contain China’s booming exports by introducing anti-dumping tariffs on the country’s exports of leather and reinforced shoes.

The punitive measures are due to be unveiled in the coming month by Peter Mandelson, the EU’s trade commissioner, and are also expected to have an impact on Vietnam in the case of leather shoes and on India for reinforced shoes, which are used mainly in the construction industry.
