Consulate General Hong Kong

My brother has sent his power of attorney fro Hong kong duly attested/signed by consulate general Hong kong .The power is yet to be verified probably the signatures of the consulate general.I visited the Foreign Affairs camp office at karachi but unable to get a proper reply. The power is to look after the interest of the doner in Pakistan and not for sale. Pls advise.
Also let me know the e-mail and mailing address of consulate office Hong kong. Regards Maqsood Akber Karachi Pakistan, Cell 0333-2104461
