Official Yerevan will fulfill all international obligations it undertook, Armenia's President said.

"If Ankara drags out ratification of the protocols, Yerevan will exercise its international rights. I have already instructed to work out amendments to the Armenian legislation referring to signature, ratification and nullifying international agreements," Serzh Sargsyan said during a joint news conference with his Latvian counterpart Valdis Zatlers.

"The more the process is protracted the more barriers will appear for normalization of the Armenian-Turkish relations," he said.
