Acting White House Chief Of Staff Mick Mulvaney told the Wall Street Journal’s CEO Council summit in Washington Tuesday that tariffs of 15% on imported goods from China are “still on the table” and could be imposed at the Dec. 15 deadline, even as both sides make progress toward a trade pact.

However, the Wall Street Journal reported earlier Tuesday that U.S. and Chinese trade officials were “laying the groundwork for a delay” of those tariffs.

The South China Morning Post reported it is "growing increasingly unlikely that a U.S.-China trade deal will be completed this week" though officials also said the Dec. 15 tariffs will be delayed.

If a company has such a fragile balance sheet that a couple of tariffs would do them in -- it’s not a company I’d invest in anyway.”

On another trade front, House Speaker Nancy Pelosi said Tuesday Democrats reached an agreement with the White House on a revised U.S.-Mexico-Canada agreement. The deal provides for stronger labor enforcement rules and environmental protections.
