Asia-Pacific economies will count on enhanced regional connectivity to stimulate trade and attract investment as the member countries seek decisive measures to improve regional economic integration, industry experts say.

"Regional connectivity is among the 21 member economies' greatest interests at the Asia-Pacific Economic Cooperation forum," said Luo Renjian, a researcher at the institute of transportation research under the National Development and Reform Commission.

Luo said the APEC economies, particularly those in Southeast Asia and South America, such as Vietnam, Indonesia, Peru and Chile, are building new platforms for broader cooperation with major APEC economies.
