"This note contained the answer of the Russian side to the question posed during the meeting of the leaders of the EAEU in a narrow format," RIA Novosti quoted Zheldibay as saying.
According to him, it was about the access of Kazakh shippers to transportation by rail of Russia at domestic tariffs.
He added that Tokayev instructed the government to continue negotiations with the Russian side on this issue on the basis of the principles of the 2015 agreement on the establishment of the EAEU.
Earlier, the chairman of the board of the Eurasian Economic Commission, Mikhail Myasnikovich, said that the heads of the EAEU member states signed 15 documents aimed at deepening integration following the summit of the association in Moscow.
