By Francesco Guarascio and Phuong Nguyen HANOI (Reuters) -New South Korean President Lee Jae Myung will host Vietnam's top leader To Lam on a visit next week, two people familiar with the plan said, as they aim to boost cooperation on technology at a time of global trade tension that could affect their ties.

South Korea and Vietnam pledge stronger trade cooperation to counter U.S. tariffs, aiming to boost economic ties and regional growth.

The two nations have pledged to nearly double bilateral trade and explore closer military ties, with expanded arms sales on the cards.
