Guyana's government is calling for face-to-face meetings with Venezuelan officials after the seizure of an American-chartered ship in disputed waters revived a decades-old territorial dispute between the two South American neighbors.

The ship was conducting a seismic survey under contract for Anadarko Petroleum Corp. on Thursday when it was stopped by a Venezuelan navy vessel and ordered to sail under escort to Margarita Island. Five American oil workers were on board.

Houston-based Anadarko said it was working with the governments of Guyana and the U.S. to secure the release of the crew and the vessel.

Guyana's Foreign Ministry Saturday said that it had requested a meeting next week to discuss the latest developments, which threaten to scare away much-needed foreign investment.

The State Department declined to comment.
