The headline is a bit misleading. The article elaborates some, for example:

In other remarks, Crosetto said that if Russian troops were to occupy Kyiv, it would "inevitably lead to a clash with other nations, which would not accept Russian tanks on their borders."

European nations have been voicing the need of peace from the beginning, it's just that the negotiating third parties can't get Russia to participate in a dialogue. Which leads to desperate stuff like France asking for China to do their part (desperate because they'd need some unlikely deal incentive to flip).
