Kazakh president cancels Armenia visit, citing cold
On Tuesday, Nazarbayev's office said Prime Minister Bakytzhan Sagintayev would travel to Armenia instead of him.
Astana's ties with Yerevan have been strained since April, when during the renewed military conflict between Armenia and Azerbaijan, Kazakhstan insisted on holding a meeting of another regional body, the Eurasian Economic Union, outside of Armenia which was due to host it.
Both Kazakhstan and Azerbaijan are Turkic-speaking, predominantly Muslim nations. Azerbaijan also tranships a significant share of Kazakh oil exports.
