In 2008, Azerbaijani president Ilham Aliyev stated that "Nagorno-Karabakh will never be independent; the position is backed by international mediators as well; Armenia has to accept the reality" and that "in 1918, Yerevan was granted to the Armenians. It was a great mistake. The khanate of Iravan was the Azeri territory, the Armenians were guests here". On the other hand, in 2009, the president of the Nagorno-Karabakh Republic Bako Sahakyan declared that "Artsakh will never be a part of Azerbaijan. Artsakh security should never be an article of commerce either. As to other issues, we are ready to discuss them with Azerbaijan.". In 2010 president of Republic of Armenia Serzh Sargsyan in his speech in the Chatham House of the British Royal Institute of International Affairs declared that "Karabakh was never a part of independent Azerbaijan: it was annexed to Azerbaijan by a decision of the Soviet Union party body. The people of Karabakh never put up with this decision, and upon the first opportunity, seceded from the Soviet Union fully in line with the laws of the Soviet Union and the applicable international law".
