Tein Domi alias Dolly, 23, who is a clerk at a medical college in China, met Amin who was studying medicine.
She claimed that both were in a relationship and that she even sold her house to pay his college fee. Last month, Amin left for Pakistan without informing her, The Express Tribune reported.
However, to Dolly's utter disappointment, Amin's family refused to welcome her at their house and did not disclose his whereabouts, the report said.
Fearing Dolly's security, police officials took her into protective custody and handed her over to the Chinese Embassy in Islamabad. However, she is refusing to return to China without accompanying Amin.
According to reports, an investigation is being carried out to trace Amin, whose family claims he is still in China.
