The White House appears to be having second thoughts on tariffs

Months ago, the White House promised to impose steel tariffs imminently but they haven't materialized.

There is a G20 steel summit in Berlin this week so it will be an issue that's back in the headlines. German economy minister Zypries said they want a multilateral deal to curb overcapacity.

Ominously, he said it's unclear if a trade war over steel can be averted. The US might not even participate in the summit.
