More attention was placed on the availability of consumer goods, and the construction of new housing was accelerated, with Honecker promising to "settle the housing problem as an issue of social relevance".

In September 1987, he became the first East German head of state to visit West Germany, where he was received with full state honours by West German Chancellor Helmut Kohl in an act that seemed to confirm West Germany's acceptance of East Germany's existence. During this trip he also journeyed to his birthplace in Saarland, where he held an emotional speech in which he spoke of a day when Germans would no longer be separated by borders, but unified under communist rule. This trip had been planned twice before, including September 1984, but was initially blocked by the Soviet leadership which mistrusted the special East-West German relationship, particularly efforts
