Opec and its allies plan to hold a meeting in March to assess their oil-production accord in Azerbaijan, and then ministers will gather to set policy in April, according to the organization’s top official. The body that reviews the implementation of Opec’s supply cuts, the Joint Ministerial Monitoring Committee, will convene in the Azeri capital of Baku on March 17 to 18, Secretary-General Mohammad Barkindo said in a statement. Ministers will then meet in Vienna on April 17 to 18 to decide whether the cutbacks should be extended beyond their scheduled expiry in the summer.
