That would appear to the implication of a complaint in a news story that:
"Trump also has spent time during the trip excusing predatory economic behavior of China and other countries and blaming past U.S. administrations for allowing the 'unfair' trade imbalances he railed against during the campaign."
This is an interesting departure from the position the Post had generally taken in both its news and editorial page in the past, which largely derided the view that our pattern of trade was in any way detrimental to the U.S. economy. In particular, the idea that other countries might be managing their currency to maintain large trade surpluses was generally trivialized and those who argued this position were derided as "protectionist." It is interesting that the Post appears to have completely flipped its position on this point.
