SIR Keir Starmer has promised Xi Jinping a more “sophisticated” relationship after years of “twists and turns” in the UK-China alliance. The PM told Xi: “China is a vital player on the global stage and it is vital that we build a more sophisticated relationship. Sir Keir Starmer said: “As one of the world’s economic powerhouses, businesses have been crying out for ways to grow their footprints in China. Mr Xi told Sir Keir the two men would “stand the test of history” if they could “rise above differences”. Tory leader Kemi Badenoch said she would not be going to China, as Sir Keir Starmer has done, if she was the prime minister.
