Guyana

President David Granger says he has received reports of what he called "extraordinary military deployments" along what Guyana considers its western border. He said Tuesday that defense officials were meeting to discuss a response.

Guyana has asked the U.N. to mediate the border dispute and Granger is expected to raise the issue at the upcoming General Assembly.

Venezuela has long claimed a resource-rich jungle territory known as the Essequibo that comprises about two-thirds of Guyana.

Speaking at a press conference ahead of a summit of the 15-member Caribbean Community, Ban said his chief of staff will meet with Venezuela's foreign minister and might dispatch a mission to both countries if there is interest. Guyana's government said last month that it planned to formally ask the U.N. to intervene.

Venezuela has long-claimed about two-thirds of Guyana and has become more insistent about a large marine area where Exxon Mobil Corp. says it made a significant oil discovery.
