Pence asked U.S. Trade Representative Michael Froman in a recent letter to look into U.S. Steel's allegations, including that Chinese steelmakers dodge tariffs by misrepresenting what country the steel comes from.
U.S. Steel has filed a trade case that could result in a ban on all Chinese imports deemed unfairly traded, The Times of Munster reported.
Pence said he favors free trade but he called U.S. Steel's allegations against China serious.
The Republican governor said nearly 23,000 Indiana residents are employed in the steel industry. He said steel is "essential" to Indiana's manufacturing-intensive economy and is also "vital" to the nation's security.
