Turkey would find it very hard to continue in a customs union with Europe if the country is excluded from a free trade deal with the United States, but quitting the union is not an option, Economy Minister Nihat Zeybekci said May 15.Turkey is pressing to be included in the Transatlantic Trade and Investment Partnership (TTIP) being negotiated between the United States and the European Union, which would cut tariffs and harmonize regulations in the world’s biggest economic blocs.Under Turkey’s current customs agreement with the European Union, the TTIP would also give the United States automatic access to Turkish markets, but Turkey’s exports would not see the same reciprocal benefit.“In that case, to continue in the customs union would be very difficult,” Zeybekci said during a visit to Washington, where he met with U.S. trade officials. A World Bank study found Turkey could gain $130 million if it were included in the TTIP but could lose up to $160 million in a one-way arrangement to drop duties on U.S. imports.But Zeybekci stressed Turkey was optimistic that its customs agreement with the EU would be upgraded to allow automatic access to any third-party trade agreements and said dropping out of the union would be like cutting off an arm.“I don’t think of this as an option,” he told Reuters. The next talks with the EU on the customs agreement are scheduled for June, he told a Brookings Institute event. The EU wants to add services, agriculture and public procurement to the deal.
