Trade ministers from 21 Asia-Pacific economies agreed Sunday on details of a study to identify challenges and ways toward the creation of a region-wide free trade zone, as they wrapped up a two-day meeting in the Philippines.

The ministers of the Asia-Pacific Economic Cooperation forum "welcome the progress on the Collective Strategic Study" on crystallizing the idea of the Free Trade Area of the Asia Pacific, they said in a statement released after the meeting on the resort island of Boracay.

"We acknowledge the importance of this study in providing useful analysis of the opportunities and challenges ahead," it said. The ministers instructed officials to report progress on the study for the ambitious free trade initiative by November when their leaders are slated to meet, with an eye to completing it by the end of 2016.
