In another sign of escalating trade tensions between China and the United States, Beijing told the World Trade Organization on Friday that Washington was failing to implement a WTO ruling against punitive U.S. tariffs on a range of Chinese goods. China's Ministry of Commerce (MOFCOM) said it had requested consultations with the United States over the issue, and anti-subsidy duties on products including solar panels, wind towers and steel pipe used in the oil industry, Reuters reported. China's complaint to the WTO was filed just days after Washington lodged a similar complaint against China, accusing it of unfairly continuing punitive duties on U.S. exports of broiler chicken products in violation of WTO rules. "By disregarding the WTO rules and rulings, the United States has severely impaired the integrity of WTO rules and the interests of Chinese industries," MOFCOM said in a statement distributed by the Chinese embassy in Washington. The case was first brought before the WTO by China in 2012 against U.S. duties on 15 diverse product categories that also include thermal paper, steel sinks and tow-behind lawn grooming equipment. In December 2014, the WTO's Appellate Body ruled in favor of Chinese claims that the products subject to duties had not benefited from subsidies from "public bodies" favoring particular manufacturers. The deadline for implementation of the rulings and recommendations of the WTO Dispute Settlement Body, set through binding arbitration, expired on April 1, according to WTO records.
