ChainCatcher news, according to Jinshi reports, after Russia announced the end of a month-long ceasefire targeting Ukraine's energy infrastructure, U.S. President Trump hinted that if the two sides cannot reach an agreement soon, he may abandon efforts for peace. "If for some reason one side creates tremendous difficulties, we can only say you are foolish," Trump said to reporters in the Oval Office on Friday. "You are fools, you are terrible, then we might as well just let it go. Of course, I hope we won't reach that point."Trump stated that he has not set a "specific number of days" for withdrawing from negotiations if an agreement is not reached, but he hopes to see rapid progress. "I can see clearly whether people are playing us," Trump said, "so I need to see a keen desire to end this. I also believe I have seen that keen desire. I think both sides have it."
