In the first decade of the twenty-first century, Turkey strengthened its international position in the region, implementing a policy of ‘zero problems with neighbours’. Strengthening the country’s position in international rela-tions meant that Turkish politicians have fallen into self-admiration, classifying their state as a kind of regional power and hoping that they can impose a vision of building a new political structure in the region. Prime Minister Erdoğan, however, broke the principle of ‘zero problems’ and his international activities have embroiled Turkey in many international problems, as a result of which the country has fallen into isolation. The government in Ankara is in conflict or has bad relations with: Egypt, Syria, Iran, Iraq, Israel, Armenia, and Cyprus. This article presents the most important international problems of Turkey with its selected neighbours – Greece, Cyprus and Armenia.
