Russia said on Monday that it would push ahead with sharp rises in import duties in the near future in spite of signing the Group of 20 communiqué that promised not to introduce protectionist measures for a year.

Dmitry Pankin, deputy finance minister, said Moscow would increase tariffs on imported cars, a move that had already been planned to protect Russian car producers. Russia has also announced a general review of trade agreements, including commitments made as part of its application to join the World Trade Organisation. The review may result in duties being increased and import quotas for sensitive products being cut.
