The British Foreign Secretary, William Hague, said that the support from Hollywood was helping to put a spotlight on the issue of rape as a weapon of war.
Dressed in black, Pitt and Jolie flanked Hague at the opening of the third day of a four-day summit in London that is the culmination of two years’ joint work by the actress and Hague.
Up to 1,200 government ministers, officials, activists and members of judiciaries and militaries, from more than 120 countries are at the summit.
The summit aims to find practical steps to punish those responsible for sex violence and help victims.
Hague said his partnership with Oscar-winning Jolie, special envoy of the UN High Commissioner for Refugees (UNHCR), had put the issue of sexual violence in conflict on the world agenda.
The foreign secretary added that the support was an example of how foreign policy could be conducted in the future.
“She brings what governments can’t … (as) there was no really big government of the world driving this,” Hague told a small media briefing including Reuters.
“You need something much more than government to be able to reach people who don’t easily listen to governments and Angelina brings that, as well as having great knowledge and passion about these issues.”
Jolie’s involvement in humanitarian issues dates back to 2001 when she travelled to Sierra Leone as a UNHCR Goodwill Ambassador.
The trip afforded her the opportunity to assess the impact of years of civil, war when an estimated 60,000 women were raped.
Her link-up with Hague came after he contacted her on seeing her 2011 directorial debut “In the Land of Blood and Honey” set against the 1992 to 1995 Bosnian war.
More than 100,000 people were killed in that conflict and an estimated 20,000 women believed raped.
The actress, 39, has attended the summit since the start on Tuesday but her partner, Pitt, joined her for the first time on Thursday for the opening plenary.
“We, as an international community, have never done enough to stop this abuse.
“And we do survivors a disservice when they know we are aware but do nothing to hold the perpetrators accountable,” Jolie told the summit on Thursday.
“Today we have an opportunity to begin to change that.” (Reuters/NAN)
