Oil tankers that were sailing toward Venezuela have turned around and others have left the country’s waters as the United States considers blacklisting dozens of ships for transporting Venezuelan oil, according to shipping data and industry sources. Chinese oil firms are considering whether to decline to charter any tanker that has visited Venezuela in the past year, no matter where the ship is now or for what voyage, four shipping sources told Reuters on Tuesday. Washington is seeking to oust the socialist government of President Nicolas Maduro by choking the oil exports that provide its main source of income.
