Laos needs consular legalisation, not an apostille
Laos is not a party to the Hague Apostille Convention. China’s accession in 2023 therefore changed nothing for documents issued in Laos, and the older chain still applies in full.
- Have the document notarised locally, by a notary public.
- Have it authenticated by the Consular Department of the Ministry of Foreign Affairs.
- Take it to the Chinese embassy or consulate for the final legalisation. This step is what makes the document usable in mainland China.
The order is fixed, because each step certifies the one before it. They cannot be done in parallel, and a step taken out of turn generally has to be paid for again.
If a service offers you an apostille for use in China on a document issued in Laos, that is not the certification mainland China requires. Certification fees are generally not refunded, so confirm the route before you pay.

What this does not cover
Certification only proves the signature and seal are genuine. It does not translate the document and it does not oblige any university to accept it. Language requirements are set separately by whoever receives the document, so confirm those first, and have any translation made after certification so the certificate is included in it.
Frequently asked questions
Do documents from Laos need an apostille for China?
No. Laos is not a party to the Apostille Convention, so an apostille is not the right certification. Documents issued in Laos need full consular legalisation, ending at a Chinese embassy or consulate.
