The United States (U.S.) and China this week initiated a trade dispute over tires, auto-parts, and poultry products just a week ahead of the 2009 G-20 trade summit in Pittsburgh, Pennsylvania.

The most recent trade policies enacted by the U.S. government includes a September 12 decision to impose a 35% trade tariff on Chinese tire imports as an anti-dumping measure. The trade policy came about as a result of a trade-complaint initiated by the United Steelworkers Union (USW) filed before the U.S. International Trade Commission. As reported by <name>Steve Levine</name> of BusinessWeek, "In [the USW's] trade complaint to the U.S. International Trade Commission, the USW invoked a provision in China's 2001 accession to the World Trade Organization (WTO) that allows protection from surging imports from the country [China]. The union documented a tripling of Chinese tire imports from 2004 to 2008 [...]" The Trade Commission initially recommended a 55% tariff however, President <name>Obama</name> agreed to only 35%. The trade tariff will be diminished by 5% per year for the next three years to 25%. The deadline for President <name>Obama's</name> decision was September 17. The trade tariff will take effect on September 26, pegging rates at the new level from the current 4%. The dispute will now move to the WTO where it can take up to 18 months for adjudication.

The two countries' executive and economic teams will meet in Pittsburgh for the G-20 meeting on September 24 and 25 to discuss these and other economic issues.
