Inspector Jian is a Chinese policeman from the Siberian border and he's a man of some influence. It would be as well not to question the source of his power as he's not above taking financial advantage of his position. When his daughter rings him from Leeds begging that he helps her he doesn't hesitate, but once in the UK he realises how difficult the search for her is going to be as he doesn't speak any English and has none of the powers which he's so used to at home. He's not going to let that stop him though.
