Australia and the WMD challenge

New technologies and the ever-increasing role of cyber warfare mean global arms control must evolve.

And, according to Department of Foreign Affairs and Trade Secretary Peter Varghese, this means a stronger role for Australia.

In delivering the 2015 John Gee Memorial Lecture at ANU, Varghese says the critical work of arms control in the 21st Century must continue and ponders the challenges diplomats will face in the future.

"However strong our record has been in the past, we're going to have to get even stronger and better at our diplomacy and strategy around arms control and disarmament in the future," he says.

For decades, Australia has been a strong, dedicated contributor to the evolution of control regimes such as the nuclear Non-Proliferation Treaty, the chemical and biological weapons conventions and the 2014 Arms Trade Treaty.
