Is the old diplomacy out-moded?

While we can trace traditional diplomacy back to the city states of Athens, the formal diplomatic institutions of today can be traced back to the fifteenth-century Italy. Traditional diplomatic features have be transformed by a more complex world of today. After the first world war, the need for a new form of diplomatic system was called for. In analysing the new form of diplomacy, we should not forget to be able to tell on what is new about the new.
Arguably, the old system is not adequate enough to contain the more complex world. Its state-centred focus is no longer adequate to deal with the different actors that have emerged.
In a globalize world, focusing on state will narrow our view of world politics, because the emergence of intense interdependence and global problems, give rooms to other non-state actors. For example, negotiations on environmental problems like global warming, proves that state-centred process of diplomacy lacks credibility due to the fact that non-state actors like Green-peace who have a great knowledge in environmental issues can not be left-out in the negotiating process. In order to give them a room, then Summitry or multilateral diplomacy is therefore important here.
However, to totally discredit the old diplomacy will be a myth, due to the fact that the New diplomacy still incorporates the structures and processes of the Old diplomacy. In the New diplomacy, what can be said to be new is the fact that secrecy is no longer seen as viable to diplomacy but open to public scrutiny, and also dissociating diplomacy from the elites alone. However, the extent to which the New diplomacy is open and taking away from the elites is debatable. For example, bilateral diplomatic relations that involves intelligence are still kept secret from the public, coupled with the fact that diplomats are still the grouping of aristocrats, believe it or not. If in doubt, then check your country diplomats. Also, the traditional institution of diplomacy, like the foreign office, embassies and joint commissions are still active and in place. Thus, to conclude that the traditional system of diplomacy is outmoded will be a fallacy. What can be gain-said, is that the traditional diplomatic institutions still endures through time , except with the fact that the more globalize, technological- advanced world with new global problems, has added or created innovations in diplomatic structures and relations and has not rendered it obsolete.
