Turkey's government has asked one of the country's top export associations to help enforce a ban on trade with Israel, slowing the flow of goods in recent weeks, according to sources. Ankara has faced criticism that trade may be continuing with Israel given a spike in exports to the Palestinian territories since the ban in May. The Trade Ministry has asked the association to require more checks and approvals of proposed shipments, including vetting with Palestinian authorities. The Central Anatolian Exporters' Association is the main approval body under the new instructions from the government.
