1969-06-25 GDR-Chile 2-1 (Halle)
Scorers: Vogel, Kreische, Gallardo
Official for Chile. Was it a GDR combined of some sort? Three days earlier a full intl was played in Magdeburg where the Chileans won by one goal.
This was a "DDR-Oberliga-auswahl" (i.e. East German League selection). Of course, this was just a label for an "experimental" national team, and the lineups for both games were similar. The first match in Magdeburg was also, to some extent, a slightly experimental lineup, as younger / untried players were called in. The result was a defeat, the first home defeat for 6 years.

After hosting Chile, the East Germany "Oberligaauswahl" went on a short tour of Sweden playing 3 games vs clubs. I think you can consider those also to be East German national team participations.
30-6-1969, IK Sirius (Uppsala) 1-3 East Germany League
(Carlsson 73' / Schütze 27', Seehaus 30', Sparwasser 52')
2-7-1969, IF Elfsborg (Borås) 1-2 East Germany League
(? / ?, Frenzel 90')
4-7-1969, Hälsingborgs IF 0-4 East Germany League
(Sparwasser 1' 31' 61', Vogel 71')
The dates may be one day out. I have lineups for DDR for the 1st and 3rd game. Perhaps you can find more info from the Swedish side.
Next was the visit of Uruguayan club Nacional, and the U.A.R. (Egypt) national team. Both played matches in Rostock during the "Ostseewoche" sports festival. Also part of this were youth matches between DDR and Finland (DDR won 1-0 in Greifswald and 4-3 in Wismar).

21-7-69 Russian SFSR 2-2 UAR
23-7-69 Dinamo Minsk 3-2 UAR
These two dates may be one or two days out.
Also I noticed this interesting game while digging these out of my untidy files:
??-7-69 Georgian SSR 0-1 "Poland Olympic team"
Reported in newspaper edition 22nd July (so probably played 2 or 3 days earlier)
Perhaps Poland played other similar matches on this trip.
