Manila, Safar 06, 1437, November 18, 2015, SPA -- US President Barack Obama on Wednesday called for the swift implementation of the Trans-Pacific Partnership (TPP), calling it the "most progressive trade deal ever," dpa reported. But he admitted that implementing the deal "is not easy to do," speaking as the leaders of the 12 TPP countries met on the sidelines of the annual Asia-Pacific Economic Cooperation summit in Manila, for the first time since the deal was concluded. "This is the highest standard and most progressive trade deal ever concluded," he said. "It includes strong protections for workers, prohibitions against child labour and forced labour," he said. "It has provisions to protect the environment, to help stop wildlife trafficking, to protect our oceans," he added. "These are enforceable provisions that can be brought to bear much as the same way any provisions related to tariffs can be dealt with." --SPA 16:01 LOCAL TIME 13:01 GMT www.spa.gov.sa/w
