The G20 summit in Buenos Aires is supposed to be the venue for a high-stakes agreement between President Trump and Chinese President Xi Jinping.

Hanging in the balance are new tariffs on everything that the U.S. imports from China. But if Trump sticks to the demands outlined by Vice President Mike Pence, there will be no deal in Argentina, just more tariffs and a trade war stalemate. Instead of trying to push China on every policy the U.S. takes issue with, Trump would be wise to get an agreement on trade and claim a quick victory.
