When planning a Vietnam investment, one of the most common questions is:

If I use a Hong Kong company, do I still need ODI filing?

It’s a reasonable assumption that structuring an investment through a Hong Kong company might bypass ODI (Overseas Direct Investment) requirements. However, in practice, this understanding is often inaccurate.

The requirement for ODI is not determined by whether a Hong Kong company is used in the structure. Instead, it depends on more fundamental factors.

A Common Misconception About ODI

Many investors assume:

“Hong Kong company = no ODI.”

This misconception usually comes from focusing too much on the investment structure, rather than the underlying regulatory logic.

In reality, regulators do not primarily assess which entity is used as an intermediary. Instead, they focus on:

1. Where the funds originate
2. Who ultimately controls the investment

Understanding this distinction is critical for avoiding compliance risks in cross-border investment.

What Actually Determines ODI Requirements

From a practical standpoint, ODI filing is determined by two key factors:

1. Source of Funds

If the investment funds originate from Mainland China, the transaction is generally considered a Chinese outbound investment, even if routed through a Hong Kong company.

2. Control of Investment

If the overseas entity (e.g., a Vietnam company) is controlled by a Mainland individual or enterprise, it may still fall within ODI regulatory scope.

These two factors form the core logic behind ODI supervision in cross-border investment.

When ODI Filing Is Typically Required

In practice, ODI filing is usually required in the following scenarios:

1. Funds are transferred from Mainland China to a Hong Kong company, and then used for Vietnam investment
2. A Mainland individual or company uses a Hong Kong entity to control or operate a Vietnam business
3. The investment is effectively managed or decided from Mainland China

For example, if an investor transfers funds from a Mainland bank account to a Hong Kong company, and then invests in a Vietnam FDI project, this would typically require ODI filing.

Even if the structure involves a Hong Kong company, the source of funds and control remain decisive.

When ODI May Not Be Required

There are also situations where ODI filing may not be necessary.

Generally, this applies when:

1. The Hong Kong company operates independently
2. All investment funds are already offshore (e.g., generated from overseas business activities)
3. No capital is injected from Mainland China
4. The structure does not involve Mainland-based control in substance

While such cases exist, they are relatively specific and depend heavily on the actual funding source and control structure.

A Practical Structuring Approach

Based on practical experience in cross-border structuring, a common and compliant approach is:

1. Establish an independent Hong Kong company
2. Assess the source of funds
3. Determine whether ODI filing is required
4. Proceed with Vietnam company registration (FDI)

This approach allows investors to:

1. Maintain flexibility in structuring
2. Ensure regulatory compliance
3. Avoid issues in fund transfer and profit repatriation

Conclusion

The key takeaway is simple:

ODI is not about the structure, it is about the source of funds and control.

Using a Hong Kong company does not automatically eliminate ODI requirements.

If the funds originate from Mainland China, or the investment is controlled from there, ODI filing is generally required. Only when funds are fully offshore and the structure is genuinely independent might ODI not apply.

For any Vietnam investment, clarifying these two factors at an early stage can significantly reduce compliance risks and operational complications later on.
