Vietnam’s Investment-Law Amendment Seeks to Balance Speed and Predictability

Vietnam wants to open more of its economy to foreign investors, and to do it faster. On 23 October, Finance Minister Ngô Văn Tuấn asked the National Assembly to amend the investment law, giving the government greater discretion to relax limits on foreign investors in restricted sectors and approve special support packages for large projects. A government decree issued this year lists 23 sectors that remain closed to foreign investors and 62 open only on conditions, from banking, telecoms and advertising to logistics, real estate and offshore wind. Some of those conditions are written into law, which until now only the National Assembly could change.

The proposal is part of a wider push. Since 2025, Vietnam’s leadership has been changing how laws are made, giving the government more scope to remove obstacles without waiting for new legislation. The Politburo’s June resolution on foreign investment calls for broader market access. The amendment would put that thinking into practice.

For investors, the appeal of speed is clear. A company that has chosen Vietnam over another location wants to begin while its cost assumptions, customer plans and financing remain intact, so every month spent waiting for a law to change has a cost. But predictability matters just as much. Investors need to understand the rules before committing capital and to trust that those rules will not shift once a plant has been built. The two aims can pull in different directions. Rules that are easy to relax today may also be easier to change tomorrow, while rules fixed in law move more slowly in either direction. No system offers both in full, and Vietnam is deciding where it wants to sit between them.

The draft includes some safeguards. Any market opening would have to protect defence and security, be transparent, apply equally to all investors and remain consistent with Vietnam’s trade agreements, which set the minimum it has promised. The Assembly’s economic committee wants more of the framework settled in advance. It has asked for the basic criteria for special packages to be written into law, for openings to be phased following a full assessment of their impact, and for continued oversight of the rules for the national investment support fund. This is the system working out its own balance between moving quickly and staying predictable.

Giving the government more discretion could allow a sector to open sooner, but the terms may be set case by case and become harder to compare, and a long-term investor will want to know what stops them from shifting later. Writing more into law would slow the process, but make more of the ground rules visible from the outset.

For an offshore wind developer considering a project that will operate for decades, the difference is material. A faster opening could bring an investment decision forward. But before committing that much capital, it still needs to know which conditions apply, whether they will endure and whether a competitor might later receive better terms. The June resolution offers some reassurance by promising that changes will not be applied retroactively against businesses, except on grounds such as defence, security and public health.

The National Assembly’s current session is due to end on 21 November. The final text will show where Vietnam draws the line between speed and certainty.
