BERLIN (AP) _ The Swimming Federations of East Germany and West Germany will hold talks next month on closer cooperation between the two sides, the official East German news agency ADN reported Monday.

ADN said the talks would be held in West Berlin on Jan. 5, to iron out ''concrete agreements,'' on possible exchange of trainers and medical aides, joint controls on doping and commercial aspects of the sport.

The brief report said the meeting was set up by the chief trainer of East Germany's Swimming Federation, Wolfgang Richter, who met with West German federation officials in Stuttgart over the weekend.

Swimming traditionally has been one of the premier sports in the mighty East German sports machine, while West Germany also has several top swimmers.

The report follows other recent reports by ADN of planned closer cooperation between the sports federations of the two countries, including soccer and tennis.
