International disputes US-EU WTO dispute In the late 1990s, the World Trade Organization authorized the United States and Canada to impose retaliatory tariffs of US$116.8 million per year on the European Union after it found the EU beef hormone ban to be in violation of the WTO Agreement on the Application of Sanitary and Phytosanitary Measures (SPS Agreement). In September 2009, the trade representatives from the US and EU signed a memorandum of understanding, which established a new duty-free import quota in the European Union for grain-fed, high-quality beef as part of a compromise solution. China In July 2007, officials of the People's Republic of China seized US-produced pork for containing ractopamine residues. Further shipments of Canadian ractopamine-fed pork were seized in September 2007. In June 2019, customs inspectors in China detected ractopamine in a shipment of Canadian pork products destined for Chinese consumption. The Chinese government thereupon suspended not only pork, but also beef imports from Canada. Canadian Agriculture Minister Marie-Claude Bibeau stated that the CRFPCP certificate was a forgery and called in the RCMP, while Canadian Public Safety Minister Ralph Goodale stressed that the federal government would vigorously defend Canadian meat producers.

This resulted in mass protests in the capital city, Taipei, by swine farmers insisting that the ban remain in place. Health Minister Hou Sheng-mou (侯勝茂)
