The United States will have majority control of 65 billion barrels of Venezuela's proven reserves in what President Donald Trump described Friday as "the biggest oil deal in world history." Caracas says the deal involves $100 billion in private investment aimed at revitalizing the industry in a country with the world's largest proven oil reserves.Interim president Delcy Rodriguez said Saturday the agreement aims to turn "cold, inert" resources underground to "a source of social and economic well-being for the people of Venezuela."But a lack of transparency is raising concerns among Venezuelans, including supporters of the government. A flood of social media comments decried loss of sovereignty, meager benefits and political costs."We don't know who this will benefit -- whether it's Venezuela or them (the United States)," said Jesus Salazar, a 68-year-old security guard. "I have my doubts, but we'll have to wait and see what happens." Venezuela's government has operated under intense pressure from the Trump administration since the US ousted and captured long-time ruler Nicolas Maduro in January.Washington allowed Rodriguez, his vice president, to stay on as interim leader so long as she toes Washington's line.Venezuela's ruling party said Saturday it supports economic measures that "prioritize national interests and make it possible to overcome the impact of more than a decade of economic sanctions, unilateral coercive measures, and unjust blockades."The party consistently blames US sanctions for the collapse of Venezuela's economy.
