WASHINGTON — U.S. President Donald Trump on Monday renewed his calls for South Korea, China, Japan and other countries to help keep the Strait of Hormuz, a key oil shipping route off Iran, open amid growing concerns over disruptions to shipping through the vital waterway. Trump made the calls during a meeting with trustees of the John F. Kennedy Center for Performing Arts at the White House, highlighting that the United States' military has "protected" allies and partners for long. Iran has effectively shut the strait, escalating concerns about the war's impact on oil prices. The waterway is responsible for about a fifth of the world's oil supplies. "We strongly encourage other nations whose economies depend on this strait far more than ours. We get less than 1 percent of our oil from the strait and some countries get much more," Trump said. "Japan gets 95 percent. China gets 90 percent. Many of the Europeans get quite a quite a bit. South Korea gets 35 percent. So we want them to come and help us with the strait," he added.
