BEIJING (Reuters) -China and Russia should jointly safeguard their security and development interests, Chinese President Xi Jinping told the visiting Russian parliament speaker on Tuesday, in their efforts to build a more "equitable" international order. The two sides should continue their traditional friendship and deepen strategic mutual trust, state-run Xinhua news agency quoted Xi as saying. U.S. President Donald Trump said earlier this week that he might impose "massive" sanctions on Russia in two weeks depending on whether progress was possible in his bid to end Russia's invasion of Ukraine.
