"One gets the sense that he's (Trump) going to be a bit tougher with China" compared with Mexico and Canada, said Paul Gruenwald, chief economist at S&P Global Ratings. The G-20 meeting of the world's developed economies takes place in Buenos Aires from Nov. 30 to Dec. 1.
Trump criticized Mexico and Canada for months, claiming they took advantage of U.S. companies through trade, but the three countries reached a new trilateral deal at the end of September to replace the North American Free Trade Agreement.
The approach to China has been different. Trump has repeatedly attacked the country for stealing intellectual property, creating barriers to American companies that try to operate in China, and for the massive trade imbalance between the two countries.
