The big overarching issue at the APEC summit is trade. China is pushing for a broad trade deal to encompass the whole region, while the U.S. is seeking a more limited one (called the Trans-Pacific Partnership) of 12 countries, China not included, the New York Times reported.

The summit also saw China and South Korea conclude a wide-reaching bilateral trade deal.
