BERLIN — Seven months after his coalition with the far right collapsed in a spectacular scandal, Sebastian Kurz, Austria’s former conservative chancellor, stood before television cameras on Thursday and announced a new government — this time with the progressive Greens.

“We chose a new path,” Mr. Kurz beamed. “It was a challenge for both sides, because the differences between the two sides are big.”

The result, he said, was a new kind of compromise. “We did not try to negotiate the lowest common denominator but consciously tried to unite the best of both worlds,” Mr. Kurz said. “That’s how it is possible that both the Greens could keep their central campaign promises and so could the People’s Party.”

Werner Kogler, the Greens leader, who will serve as vice chancellor, put it more bluntly: “We were elected for different things.”
