The UK and Taiwan pushed back on an op-ed in The Telegraph by China’s ambassador to Britain Zheng Zeguang, invoking UN Resolution 2758 to argue that Taiwan has never been a country. The UK foreign office and Taiwan's unofficial embassy in London gave official responses to Zheng's op-ed, dismissing his claims. The diplomatic row comes as UK-China ties fray from a recent spy case and controversy over plans for a large new Chinese embassy complex in London.
