In 1964, Paul VI created a Secretariat for non-Christians, later renamed the Pontifical Council for Interreligious Dialogue and a year later a new Secretariat (later Pontifical Council) for Dialogue with Non-Believers. This latter was in 1993 incorporated by Pope John Paul II in the Pontifical Council for Culture, which he had established in 1982. In 1971, Paul VI created a papal office for economic development and catastrophic assistance. To foster common bonds with all persons of good will, he decreed an annual peace day to be celebrated on January first of every year. Trying to improve the condition of Christians behind the Iron Curtain, Paul VI engaged in dialogue with Communist authorities at several levels, receiving Foreign Minister Andrei Gromyko and Chairman of the Presidium of the Supreme Soviet Nikolai Podgorny in 1966 and 1967 in the Vatican. The situation of the Church in Hungary, Poland and Romania, improved during his pontificate.
