As some U.S. companies anticipate a coup in Venezuela, which could open the door for new business opportunities, others are screening their transactions for potential sanctions-related risks, according to international trade lawyers.

In January, the U.S. announced it would impose new sanctions on Venezuela’s state-owned oil company Petróleos de Venezuela SA, or PDVSA, the parent company of Citgo and several other subsidiaries, as part of an effort to pressure Venezuelan President Nicolas Maduro to resign.
