I am a Pakistani national and want to visit my friend in china (Shenzhen). I may need to visit Beijing and Shanghai as well during my stay. I understand individual tourist visas are not accepted for Pakistani nationals. I also know the documentation requirements and I can have an invitation letter from her along with other documents required from there. As she is my friend, how can I produce the certificate of the relationship between me and her (the person in China I want to visit) as she is just my friend. In this case, which document will serve the purpose. I will really appreciate your expert opinion on this concern. Kind Regards,
