VIENNA, Jan. 2 (Xinhua) -- Austria's conservatives and the Greeens agreed to form a coalition government on Wednesday, ending almost three months of negotiations.

The agreement means Austria will have the left-wing Greens in government for the first time.

"We have reached an agreement," Sebastian Kurz, Austria's former chancellor and leader of conservative People's Party, told reporters in a joint press conference with Wener Kogler, his counterpart from the Greens.

The two will become chancellor and vice chancellor of the upcoming government, though the Greens, in a junior role, could gain just four of 15 ministries. But they did not unveil details of their plan.
