Security, trade, aid and cultural ties are among subjects Cuban President Fidel Castro is due to discuss with Caricom leaders at a summit in Barbados. Its the second of these triennial summits, which began in 2002 to mark the 30th anniversary of the establishment of diplomatic relations between Cuba and Caricom nations. Mr Castro was expected to lay a wreath at a memorial to those killed in the bombing of a Cubana Airlines flight off Barbados in 1976. The attack was allegedly masterminded by an anti-Castro militant now fighting expulsion from the United States. Both Venezuela, where the flight originated, and Cuba, have requested the extradition of Luis Posada Carriles. Caribbean leaders have called on the US to bring him to justice. Earlier this year, they called Mr Posada Carriles "the primary suspect" of "the most horrific act of terrorism ever experienced by the countries" of the Caribbean. Assistance Caribbean journalist Rickey Singh told BBC caribbean Radio that Cuba will also be looking to its neighbours to buy more Cuban goods. He said while Cuba wasn't necessarily looking for much in return, it already provides significant assistance to Caribbean governments in health services and education. Meanwhile, Caricom leaders met ahead of the summit to discuss preparations for the Jan. 1 start of the Caribbean Single Market. The CSME, as it is called, will allow skilled workers to migrate in search of jobs more easily between member states. It will also intended to remove barriers to trade and investment among member territories. Reprinted from bbccaribbean.com
