Chinese companies looking to sign long-term agreements to buy crude oil from U.S. oil exporters have virtually disappeared, the chief executive of Enterprise Products Partners LP said on Tuesday.  The United States and China have been embroiled in an increasingly bitter trade dispute for nearly a year, and it escalated recently with the U.S. imposition of 25% tariffs on $200 billion of Chinese goods.

The trade war has all but shut down shipments of U.S. crude to China, and it is unlikely Chinese buyers will sign long-term offtake agreements with U.S. crude exporters right now, Enterprise CEO Jim Teague said on the sidelines of a Houston energy industry conference.  “When I was in China, I heard two words at every meeting: ‘Trump’ and ‘tariffs,’” Teague said.
