South Korean President Park Geun-hye was to hold a summit with Indonesian President Susilo Bambang Yudhoyono on Saturday that is expected to center on buttressing the fast-expanding economic cooperation between the two countries with a free trade deal. South Korea and Indonesia launched negotiations to forge a comprehensive economic partnership agreement (CEPA) last year and have since conducted five rounds of talks. A CEPA is the equivalent of a free trade pact designed to tear down or lower barriers to trade.
