Colombia has postponed the scheduled restoration of diplomatic ties with Ecuador amid an ongoing dispute that erupted after Colombia staged a cross-border raid into its neighbor's territory.

Ecuador responded to the announcement by saying it may impose trade restrictions on Colombia.

The two countries were to have restored ties this week at the level of charges d'affaires, in a deal brokered by former U.S. President Jimmy Carter. Colombia, however, described recent comments by Ecuadorean President Rafael Correa as offensive and delayed the move.

Mr. Correa said in a recent interview that Colombia would have to fully explain the raid and that the bombs used were American. He said his country would be the one to set a timetable for re-establishing relations.

Colombia's raid into Ecuador in early March killed a commander of Colombia's FARC rebels.

Colombia says computer files found during the raid link Ecuador and Venezuela to the FARC, a charge both countries deny.

The United States, Colombia and the European Union have designated the FARC as a terrorist organization.
