HANOI, May 2 (Reuters) – Japanese Prime Minister Sanae Takaichi is set to meet Vietnam’s leader To Lam in Hanoi on Saturday as the countries ​try to shore up ties amid a sharp ‌slowdown in Japanese investment in Vietnam.

The two sides are expected to discuss ways to deepen a Comprehensive Strategic Partnership established in 2023, with a focus on cooperation in energy, technology, critical ‌minerals ​and regional stability, a Japanese foreign ⁠ministry official said.

Japan remains ⁠one of Vietnam’s largest foreign investors, with many Japanese multinationals operating large manufacturing facilities in the country. However, new Japanese investment pledges in the first quarter ​fell about 75% from a year earlier to $233 million, Vietnamese government data shows.

Takaichi is expected to press ⁠for improvements in Vietnam’s business ⁠environment and discuss the challenges facing Japanese ​companies, including delayed payments for completed works and difficulties gaining ​access to large infrastructure projects, the official said.

Japan ‌last year announced it would withdraw from a nuclear power project in Vietnam, citing an overly restrictive construction timetable.

Days before the visit, Hanoi said it was reconsidering ⁠a ban on petrol-powered motorcycles in its city centre, a policy long criticised by Honda.

Despite investment concerns, bilateral trade has ⁠remained strong, rising ‌12.3% from a year earlier to $13.7 ⁠billion in the first quarter, according to ​Vietnamese ‌customs data.

Takaichi is also scheduled to meet ​her Vietnamese ⁠counterpart Le Minh Hung and deliver a speech at Vietnam National University on the evolution of Japan’s “Free and Open Indo-Pacific” strategy, before travelling on to Australia.
