Full story: BBC NewsThe UK is stepping up attempts to secure an anti-whaling majority on the International Whaling Commission (IWC).
Last year, pro-hunting nations gained their first IWC majority for 20 years.
The British government will publish a brochure this coming week aimed at encouraging nations opposed to whaling to join the Commission.
It says whales are "sensitive, social creatures", with some species risking extinction. Japan says these arguments are "old rhetoric and half-truths".
