ADDIS ABABA - Russia believes that a possible meeting between US President Donald Trump and North Korea leader Kim Jong Un 'is a step in the right direction,' foreign minister Sergei Lavrov told reporters while on a visit to Ethiopia. 'It should not just be a meeting, it should open up a way to resuming a fully fledged diplomatic process to find a solution to the North Korean nuclear issue on the basis of principles agreed during the six-party talks and the UN Security Council,' Lavrov said.
