There is no need to use gender quotas in international affairs. If a woman is qualified to assist as a negotiator or has a relevant skill set appropriate to the occasion then yes engage her for the position. But to bring on a woman just for the purpose of being a woman demeans those who work hard to gain the necessary skills and allows those with political connections to get notified more easily. The goal of any negotiation is to have the best qualified team at your beck and call. Not the most politically correct team to play well in the press.
