We have reconfirmed the unity and firmness of our position, the position expressed in the Joint Communique of the four powers at Paris on December 14th. We do not accept any substitution of East Germans for the Soviet Union in its responsibilities toward Berlin and its obligations to us. We are resolved that our position in, and access to, West Berlin shall be preserved.
