Washington, June 24: The experts at a leading US think tank said Chi’s trade protection is not significantly above that in large high-income economies like the United States. US Commerce Secretary Wilbur Ross labelled Chi as “the most highly protectionist of the big countries” in his recent interview with the Wall Street Jourl. His Chi-bashing rhetoric, however, was refuted by two economists with Peterson Institute For Intertiol Economics (PIIE), Xinhua news agency reported on Saturday. In an online article recently published on PIIE website, senior fellow Nicholas Lardy and research alyst Zixuan Huang argued that Ross’s accusation was outdated and neglected the progress Chi had made over the last three decades.
