In the material for the publication "Ukrainian Truth", the ex-president of Ukraine gave some advice to the current leader of the country.

So, Poroshenko did not recommend Zelensky to discuss the “gas issue” at the summit in order to “prevent Russia from forming an unprofitable package of agreements for Ukraine, according to which Ukraine would make important concessions in the political track for cheap gas.”

“The most important piece of advice: don't trust Putin ... I’d advise you to avoid meeting face to face with Putin,” he wrote.

Earlier, Poroshenko’s faction “European Solidarity” proposed Zelensky to discuss “red lines” that are “unacceptable to cross” before the summit in the Norman format.

On December 2, Zelensky said that the Norman-format summit, which will be held in Paris on December 9, is a good opportunity to start a dialogue on the situation in the Donbass.
