International Monetary Fund chief Christine Lagarde led an attack by global economic organizations on U.S. President Donald Trump¡¯s ¡°America first¡± trade policy on Monday, warning that clouds over the global economy ¡°are getting darker by the day.

Trump backed out of a joint communique agreed by Group of Seven leaders in Canada over the weekend that mentioned the need for ¡°free, fair and mutually beneficial trade¡± and the importance of fighting protectionism.

The U.S. president, who has imposed import tariffs on metals, is furious about the United States¡¯ large trade deficit with key allies. ¡°Fair trade is now to be called fool trade if it is not reciprocal,¡± he tweeted on Monday.
