Russian President Vladimir Putin has spoken with Chinese President Xi Jinping, emphasizing the two countries' close ties a day after Donald Trump was sworn in as the 47th U.S. president.

The head of Russia's $23 billion sovereign wealth fund praised U.S. President Donald Trump on Tuesday, saying his raft of orders showed that decisive leadership could change the course of history, boost growth and open opportunities for dialogue.

The EU's top diplomat and Poland's prime minister said Wednesday that the bloc must heed US President Donald Trump's demand to spend much more on defence -- faced with the "existential threat" posed by Russia.

Russian President Vladimir Putin congratulated U.S. President-elect Donald Trump on taking office hours before Trump's inauguration in Washington and said he was open to dialogue with the new U.S. administration on Ukraine and nuclear arms.

His inauguration speech was loudest in its silence on Ukraine. But hours later, US President Donald Trump laid bare – in a trademark casual, rambling fashion – his position over the war in Ukraine. And it was tougher on the Kremlin than you might expect.

He has worked at the U.S. Department of State, on the National Security Council, and as a foreign policy adviser to U.S. Senator John McCain. Today, U.S. President Donald Trump will sweep back into power promising a new American approach to the world.

Chinese leader Xi Jinping vowed to take his country’s ties with Russia to a new level this year in a video conference with counterpart Vladimir Putin on Tuesday, hours after the inauguration of US President Donald Trump.

Trump has offered little insight into how he intends to fulfill his campaign pledge to end the fighting between Russia and Ukraine.

Alexander Lukashenko, the president of Belarus, has criticized Trump's inauguration speech, the executive orders he signed, and more.
