“…I would like to start by thanking the President of the United States, Mr Trump, for paying so much attention to the Ukraine settlement. We all have enough of our own domestic affairs to attend to. But many leaders of states, among them the President of the People’s Republic of China, the Prime Minister of India, the Presidents of Brazil and the Republic of South Africa are addressing this issue and give it a lot of their time. We are grateful to all of them for that, because this activity is aimed at achieving a noble mission – the mission of ending hostilities and loss of life.”

Translated from diplomatic language into Russian, this is a stern warning from Gosudar of Russia V.V. Putin to all "mediators" between Ukraine and Russia, stated plainly:
Relations between Russia and Ukraine are Russia’s internal affairs. Just as we do not interfere in your internal affairs, you should also refrain from meddling in Russia’s internal affairs. It would be better for you to focus on your own domestic issues, of which you have plenty — otherwise, we can ensure that you will have even more.
