Manufacturing companies entering China face a dilemma. They need to share production specifications, design files, quality control procedures, and sometimes source code with their Chinese operation — whether it’s their own WFOE, a contract manufacturer, or a joint venture partner. But sharing that information creates the risk that it walks out the door.
Trade secret protection in China has improved, both in the legal framework and in the courts’ willingness to enforce it. The 2019 amendment to the Anti-Unfair Competition Law increased the maximum statutory damages for trade secret misappropriation to RMB 5 million and introduced punitive damages of up to five times the actual damages. The 2020 US-China Phase One trade agreement included commitments on trade secret protection that have been implemented through judicial interpretations and enforcement guidance.
But legal remedies are reactive — they kick in after the secret has been stolen. The practical protection strategy for a manufacturing company needs to prevent the theft from happening in the first place.
What Qualifies as a Trade Secret
Chinese law protects technical information and business information that is not publicly known, has commercial value, and is subject to reasonable measures to maintain its confidentiality. This is broadly consistent with the definition of trade secrets in most jurisdictions.
Technical information includes manufacturing processes, formulas, design drawings, software source code, quality control methods, and testing data. Business information includes customer lists, supplier databases, pricing strategies, marketing plans, and financial projections.
The key requirement is reasonable measures to maintain confidentiality. A company that claims its manufacturing process is a trade secret but hasn’t taken steps to protect it — no confidentiality agreements with employees, no access controls on the factory floor, no marking of confidential documents — will struggle to convince a Chinese court that the information was a trade secret when it was allegedly misappropriated.
The Employee Threat
The most common trade secret misappropriation in China involves employees. A production manager leaves the WFOE, takes the process parameters and quality control specifications to a competitor, and the competitor starts producing an identical product at a lower cost because it didn’t have to do the process development.
The protection starts before the employee is hired. The employment contract should include a confidentiality clause that is specific — identifying the categories of information that are confidential, not just a boilerplate clause saying that all information about the company is confidential. The confidentiality obligation should survive termination of employment.
During employment, access controls matter. The production parameters for the most sensitive processes should not be accessible to every employee who works on the line. They should be accessible to the people who need them and no one else. Physical access to areas where confidential processes are performed should be restricted. Documents containing confidential information should be marked as confidential and tracked.
After employment, the employee’s departure should trigger a review of what information the employee had access to and whether any of it has left the company. The exit interview should include a reminder of the continuing confidentiality obligation. The employee’s devices should be checked — with appropriate privacy safeguards — for company information.
The Contract Manufacturer Threat
A foreign company that contracts with a Chinese manufacturer to produce its products is sharing its trade secrets with a company that may also produce for its competitors. The contract manufacturer’s employees move between production lines for different customers, and information moves with them.
The protection strategy starts with the manufacturing agreement. The agreement should specify exactly what information is confidential, limit the manufacturer’s use of the information to the purpose of fulfilling the contract, require the manufacturer to maintain confidentiality through technical and organizational measures, and prohibit the manufacturer from using the information to produce products for other customers.
The agreement should include audit rights. The foreign company should have the right to inspect the manufacturer’s facilities to verify that the confidentiality measures are in place. An audit that’s actually exercised — not just a right on paper — sends a signal that the foreign company takes trade secret protection seriously.
The agreement should also include a non-compete obligation for the specific product category. A manufacturer that has been given the specifications and process parameters for a customer’s product should not be free to produce an identical product for another customer, even if it doesn’t technically copy the confidential information. The non-compete obligation is conceptually separate from confidentiality — it doesn’t require proving that information was used — and it’s enforced through a contractual penalty clause.
Physical and Technical Protection
The physical security of documents and access is important in a manufacturing environment where paper documents and physical samples are still commonly used. Confidential documents should be kept in locked storage when not in use. Documents that are no longer needed should be shredded, not recycled. Samples of products and materials that embody confidential information should be stored securely and accounted for.
In the digital environment, network segmentation matters. The design and engineering systems should be on a separate network from the general office systems. Access to confidential technical information should require multi-factor authentication. USB ports on computers that access confidential information should be disabled or monitored. Email systems should be configured to detect and block the transmission of large attachments to external addresses.
The Chinese subsidiary’s IT systems should be subject to the same security standards as the parent company’s systems. A common mistake is to treat the China operation as a low-security environment because “it’s just a factory.” The factory has the most valuable information — the process parameters, the tooling specifications, the quality control data — and it needs the highest level of protection.
The Legal Fallback
When prevention fails, the legal response needs to be quick. A foreign company that suspects trade secret misappropriation should move to preserve evidence immediately. The Chinese courts can grant preliminary injunctions in trade secret cases, but they require evidence that the trade secret exists, that the defendant has access to it, and that the defendant is using or is about to use it.
Evidence collection in a trade secret case is challenging because the evidence is usually in the hands of the alleged misappropriator. The plaintiff needs to gather what it can from its own records — access logs, email records, departure documents — and present a case that is specific enough to justify discovery or investigation.
The 2019 amendment to the Anti-Unfair Competition Law shifted the burden of proof in certain circumstances. If the plaintiff can show that the defendant had access to the trade secret and that the defendant’s product or process is substantially identical to the plaintiff’s trade secret, the burden shifts to the defendant to prove that it developed the product or process independently. This is a significant procedural advantage for plaintiffs and reflects the legislature’s recognition that trade secret misappropriation is difficult to prove directly.
Criminal enforcement is available for trade secret theft. The public security authorities have the power to investigate and prosecute trade secret theft, and the penalties include imprisonment for serious cases. A criminal complaint can be a powerful complement to civil litigation because the authorities’ investigative powers exceed a civil litigant’s discovery rights.
