In a speech at South Korea's Yonsei University, Lam urged South Korean companies to keep investing in Vietnam and warned of the risk of fragmenting supply chains. "Vietnam welcomes South Korean enterprises to expand their investments in the country, emphasising substantive cooperation in technology," Lam said.

South Korea and Vietnam pledged deeper economic and strategic cooperation as their leaders held a summit on Monday, with the countries seeking to leverage their business ties to navigate a challenging global trading environment.
