Talks began to fell apart in 2012, with Ban Ki-moon stating that "there is not enough progress on core issues of reunification talks for calling an international conference". Special Advisor of the Secretary-General Alexander Downer further commented that "If the Greek Cypriot and Turkish Cypriot Leaders cannot agree with each other on a model for a united Cyprus, then United Nations cannot make them". Eroglu stated that joint committees with the Greek Cypriot side had been set up to take confidence-building measures in September that year, but negotiations were suspended in early 2013 because of a change of government in the Greek Cypriot community of Cyprus. On 11 February 2014, Alexander Downer, UN Secretary-General's special adviser, stepped down. The Greek and Turkish Cypriot leaders declared a Joint Communique.
