Direct answer

The clause is useful, but it is not a substitute for trade-secret hygiene or an NNN package.

Parties may agree to keep defined information confidential, limit use, and return or destroy files. To treat information as a trade secret under Anti-Unfair Competition Law, you still need secrecy measures and information that is not generally known. A thin one-paragraph NDA, no marking, and open WeChat sharing will undermine both the clause and any later trade-secret claim. Mandatory reporting to regulators, stock exchanges or courts is usually carved out. Employment confidentiality and post-termination non-competes are separate tools.

The signal ledger.

These facts move the question beyond a label and into a product, money-flow and control analysis.

Signal
Ask the operating question
Why it changes the route
Trade secret vs contract
Do you need AUCL trade-secret remedies, or only a contractual damages claim?
The evidence and secrecy-measure tests are stricter for trade secrets.
Factory and vendor chain
Will drawings go to a China OEM, a sub-supplier, or a trading company?
A clause that does not bind the actual factory is a hole.
Mandatory disclosure
Could SAMR, tax, a court or a listed-company disclosure force production?
The clause should manage notice, not purport to block lawful process.
Prepare before you escalate

Bring a compact evidence docket—not a pitch deck.

Give a compliance team or counsel the operating facts that reveal the perimeter.

Common confusions

Questions people ask before they build.

Short answers for orientation. The right result can change with the service model and current rules.

Is a confidentiality clause the same as an NNN?

No. An NNN package typically adds non-use and non-circumvention aimed at China manufacturing. A generic keep-secret paragraph is thinner.

Can we stop an employee using know-how after they leave?

That is mainly employment confidentiality, garden leave and, if paid correctly, non-compete—not only a commercial NDA with the company.
