[Controversy over restrictions on diesel exports heats up. U.S. Energy Secretary reportedly reminds industry to prepare] On September 24, U.S. Energy Secretary Chris Wright told oil industry executives that in view of the increasingly fierce discussions within the Trump administration on restricting diesel exports, preparations should be made for the possibility of taking this measure. Wright delivered the message to business executives in a phone call late Tuesday, hours after Trump said he had urged administration officials to consider restrictions on diesel exports, people familiar with the matter said. Discussions around restrictions on diesel exports continued on Wednesday, but no final decision had been made. Trump's core aides are divided over the decision, with oil executives warning the White House that any ban would ultimately lead to higher global prices. Wright highlighted a possible voluntary solution on Wednesday, saying the government still wanted to help the industry increase its own supply of diesel even without a ban on diesel exports.
