british citizens and bn(o)s who are of full or partial chinese descent are also chinese nationals under chinese law unless they have renounced their chinese nationality with the hong kong sar government. as china does not recognise multiple nationality, those persons are considered by china as solely chinese nationals before and after the handover of hong kong and hence are not eligible for consular protection when on chinese soil. although holding the same nationality under the chinese nationality law, chinese nationals with a connection to hong kong or macau have been categorised differently from chinese nationals domiciled in mainland china.
