The two countries have held five rounds of talks on a comprehensive economic partnership agreement to lower trade barriers, Yonhap news service reported Saturday.
"We need a firm institutional framework if South Korea and Indonesia are to achieve the goal of expanding trade volume to $100 billion by 2020," Park said during a meeting in Jakarta that included business leaders from South Korea and Indonesia.
"The South Korean government will consult closely with the Indonesian government to conclude a comprehensive economic partnership agreement at the earliest possible date," the president said.
