I'm translating some trading documents for a Vietnam company and I read this:<br/><br/><u>On processing behalf of</u> Party A: ABC Co., Ltd.<br/>Address: D1 Rd, Binh Duong, Viet Nam<br/><br/>Is the underlined phrase correctly written? I've read phrases such as 'on his behalf', 'on what behalf', but never 'on ***ing behalf of'.
