The three areas of diplomacy , security , trade and environment are all every states concern and even though they are in some way connected to each other they operate differently. Generally , security can be thought of in terms of stability of a state and safety of its citizens , but in order to have that , if there are any concerns such as threat to a state the first response and action will be through negotiation, if that's possible, using soft power , mainly hesitate using hard power for public safety .
Security diplomacy is arguably one element of diplomacy that has maintained the discreetness and privacy, that being the case, it mainly takes place bilaterally and its closest to what is so called the 'old diplomacy' , and that shows how it is still effective and useful. The negotiation happening without the media and public eye is for the national interest and the safety of its citizens. As history has proved , there are examples of state leaders using back-channels to come into agreement to prevent the use of hard power.
Trade is an important factor to diplomacy and it has undergone some changes , first of all an increase in the coverage of trade policy to include new issues by bringing new policy area such as (investment , consumer protection ,food safety etc) with an increase in the number of actors or interests concerned with trade policy. As a result the trade policy makers must now deal with a wide range of different actors and it has become more complex. Developments since the conclusion of Uruguay Round of trade negotiations suggest a mixed picture with regard to the ability of policy makers to cope with new challenges. The Doha Development Agenda (DDA) negotiations were successfully launched in 2001, despite the start of a new multilateral round , however regional and bilateral has continued with WTO member actively engaging in negotiating trade agreements.
Environmental diplomacy can be broken into two categories , national resources and pollution . In each case the main problem is that political boundaries rarely reflect biological boundaries, so that as national economies consume resources and produce pollution , they spread environmental problems far beyond their national boundaries. Unites States has been one of the leading nations in environmental diplomacy , but as global discussions produced treaties that were unacceptable from US part , there was a shift from away from bilateral to multilateral and open to every nation. That shift has been a logical reaction to an increasing international awareness that some of the biggest threats to human society derive from global environmental problems. In addition , the increase in scientific knowledge and the awareness of public and faith in science were crucial elements in dealing with environmental problems.
Finally the NGOs have a done a fantastic job when it comes to environmental problems and always finding a way to cope with it.
