In addition, the [[University of Vienna]] hosts the annual [[Willem C. Vis Moot]], an international commercial arbitration competition for law students from around the world.

Diplomatic meetings were frequently held in Vienna in the latter half of the 20th century, resulting in several significant documents bearing the name [[Vienna Convention (disambiguation)|Vienna Convention]]. Among the most important documents are the 1969 [[Vienna Convention on the Law of Treaties]], as well as the 1990 [[Treaty on Conventional Armed Forces in Europe]]. Vienna also hosted the negotiations leading to the 2015 [[Joint Comprehensive Plan of Action]] on Iran's nuclear program, as well as the [[Vienna peace talks for Syria]].

=== Charitable organizations in Vienna===
Alongside international and intergovernmental organizations, there are dozens of charitable organizations based in Vienna. One such organization is the network of [[SOS Children's Villages]], founded by [[Hermann Gmeiner]] in 1949. Today, SOS Children's Villages are active in 132 countries and territories worldwide. Others include [[Help Afghan School Children Organization]] (HASCO).
