China on Tuesday refuted allegations that an Indian woman from Arunachal Pradesh was harassed at Shanghai airport, saying the actions taken by the Chinese immigration officials were as per laws and regulations.

Pema Wangjom Thongdok, a UK-based Indian citizen who was travelling from London to Japan on November 21, claimed that her three-hour scheduled layover turned into a traumatising ordeal after immigration personnel declared her passport "invalid" solely because it listed Arunachal Pradesh as her birthplace.
