The China Embassy Attestation is essential and compulsory proof to legalize the use of documents like your personal, educational and commercial while you are in China. The purpose of attestation is simple: it is to verify if you are in the country legally and the legitimacy of the documents. Please note that completing that attestation alone would allow you to use the document while you are in China. The attestation process is mainly certified by the authorization body, like the China embassy, but in the initial stage, the applicant must complete the State and MEA Attestation in India. Since China is not a member of the Hague convention, the document issued by the Indian Government should be attested by the China embassy.
