text: LONDON (Reuters) - U.S. Commerce Secretary Wilbur Ross said there was nothing improper about his investments in a shipping firm with significant ties to Russian President Vladimir Putin’s inner circle, a BBC journalist reported on Monday.  U.S. media, citing leaked documents from an offshore law firm, said partnerships used by Ross have a 31 percent stake in Navigator Holdings, which the New York Times said earns millions of dollars a year transporting gas for Russian petrochemical firm Sibur. “The fact that (Sibur) happens to be called a Russian company does not mean there’s any evil in it,” Ross said, according to a BBC journalist on Twitter reporting the content of an interview with Ross.
