The WTO appears cautious about overlapping membership in several blocs that could impede trade flows with multiple trade rules. It was also concerned that, while many older trade agreements only included tariff liberalization and related rules such as trade defence (e.g. B anti-dumping and anti-subsidy), standards and rules of origin, more recent agreements will be extended to areas such as service rules, investment, competition, intellectual property rights and more. “This could create regulatory confusion and implementation problems,” the WTO says. In 1823 the Reciprocity of Duties Act was passed, which strongly supported the British carry trade and allowed for the mutual abolition of import duties under bilateral trade agreements with other countries. The Transatlantic Trade and Investment Partnership (TTIP), the Trans-Pacific Partnership (TPP) and regional cooperation in Asia and the Pacific (RCEP) account for a significant share of global GDP and global trade, indicating that regionalism could become a broader and multilateral framework. . . .
