A senior official with Venezuelan state-run oil firm Pdvsa Tuesday said it was "feasible" that Caracas ceased oil sales to the United States -its largest oil buyer-, but conceded that such a move would have a high price for the two nations, Reuters reported.

"It is feasible, but it has a cost," said Pdvsa's outside director Bernard Mommer in an interview with official television channel VTV. He added that such a move could entail "economic disarrangements," and could have a cost for the two countries.

When asked if halting oil supplies to the world's largest economy was possible in short time or the long time, Mommer replied, "I do not want to make any comments about that right now. But let's say that it will always result in economic disarrangements. However, it is feasible. It is possible."

The official conceded the move would not be desirable as, "that would cost us and the other party a lot of money."

Last Sunday, Chávez reasserted his threat to discontinue oil supplies to the US, after US oil major Exxon Mobil last week won court orders freezing over USD 12 billion in Pdvsa's assets and accounts, amidst a legal battle following nationalization by the Venezuelan government of Exxon Mobil's heavy-crude oil projects in Venezuela in 2007.

Venezuela reassured customers that such a ruling would undermine neither its operations nor its finances. According to Chávez, Exxon Mobil is another player in "an economic war" conducted by the "US empire" to unseat his government.
