Turkish Foreign Minister Ahmet Davutoglu and U.S. Secretary of State Hillary Clinton discussed the Protocols signed in October 2009 by Turkey and Armenia, diplomats said on Wednesday.

Davutoglu and Clinton, who both are in London to attend an international conference on Afghanistan, had a 15-minute brief meeting, diplomats said, Anatolian Agency reported.

The Protocols aimed at normalization of bilateral ties and opening of the border between Armenia and Turkey were signed in Zurich by Armenian Foreign Minister Edward Nalbandian and his Turkish counterpart Ahmet Davutoglu on October 10, 2009, after a series of diplomatic talks held through Swiss mediation.

On January 12, 2010, the Constitutional Court of the Republic of Armenia found the protocols conformable to the country’s Organic Law.
