Turkey believed that by signing protocols with Armenia and clearly indicating its readiness to open the border, the Armenians could somehow be cajoled or pressured into resolving the Nagorno-Karabakh problem more quickly or cede territories surrounding Nagorno-Karabakh.
Das Problem dabei ist, dass die Türkei die Grenze ursprünglich genau wegen Berg-Karabach und nicht wegen irgendeiner bilateralen Frage geschlossen hat.
