It's been going on for far longer than that and pretty much since the late 1940's.
And while Brandt was eventually replaced by the more conservative (but still social democrat) Helmut Schmidt, the general strategy of mutual economic dependency was upheld, and contributed to the eventual reunion of both Germanies.
In general, back then this strategy worked so well, that even the chancelors from the conservative CDU didn't feel compelled to change it.
Even Merkel, while far more cool and restrained towards russia than her predecessor, did not really change much in that regard. Kinda expected from a conservative though...
Coincidentally the first reduction came with a change of power from the SPD/Greens coalition to the CDU/FDP and the second slump when the energy and business ministry went from the SPD in the coalition to Peter Altmaier of the CDU.
In a recent debate on energy in parliament the current chancellor from the SPD (labor equivalent) responded to criticism from the CDU (conservatives), that the current government is fixing the huge mess left over by the previous governments (lead by the CDU). I'm not a big fan of Olaf Scholz (the current chancellor) in general, but rarely was there a truer statement.
