Donald Trump has said Venezuela "will be turning over" up to 50 million barrels of oil to the US, after a military operation to remove President Nicolás Maduro from power. The oil - worth about $2.8bn (£2.1bn) - will be sold at its market price, the US president wrote on social media, adding he would control the money raised and use it to benefit the people of Venezuela and the US. His comments come after he said the US oil industry would be "up and running" in Venezuela within 18 months and that he expected huge investments to pour into the country. China, which has been the biggest buyer of Venezuelan oil in recent years, has condemned Trump's announcement as well as the US's reported demands that Venezuela gives its oil exclusively to them. "This Oil will be sold at its Market Price, and that money will be controlled by me, as President of the United States of America, to ensure it is used to benefit the people of Venezuela and the United States!" His comment came a day after Rodríguez, formerly Venezuela's vice-president, was sworn in as its interim president. Maduro has been brought to the US to face drug-trafficking and weapons charges.
