Innovation knows no national boundaries, Li said, calling for better connection of the two countries' respective innovation strategies.

China and South Korea should strengthen their coordination and communication on policies, laws and regulations, provide more cooperation platforms for their entrepreneurs, and join hand to explore third-party markets, Li added.

Li arrived in Seoul on Saturday for a three-day trip, which also included a trilateral summit with Japanese and South Korean leaders on Sunday.
