The International Whaling Commission has ended its four-day annual meeting having chipped away at still-considerable differences between whaling nations like Japan and antiwhaling countries.

The issues dividing the two camps are over a set of guidelines to regulate commercial whaling.

The IWC passed a resolution by consensus with some reservations to work further on the text of a Revised Management Scheme for commercial whaling, a topic that has not moved forward in the last 13 years.

The resolution calls for a working-group meeting in February to continue work on the management scheme, a set of legal and scientific guidelines to regulate commercial whaling.
