The US also has accused China of breaching World Trade Organization (WTO) rules and used it as a pretext to take unilateral measures against China. China has fulfilled its WTO commitments, having eliminated import quotas, import licenses, specific import tendering requirements and other non-tariff measures by 2005. As China slashed customs duties on automobiles in accordance with its WTO commitments, China's domestic auto industry, which had lagged developed members before China's WTO accession, took a heavy blow. China supports WTO members to solve their trade disputes within the WTO dispute-settlement mechanism. It redressed other members' violations of obligations and defended the authority of WTO rules by lodging complaints in the WTO while it actively defended the cases against China and complied with WTO rulings.
