China’s Pan Zhanle accused Australia's Kyle Chalmers of snubbing him on the opening night of competition and American swimmer Jack Alexy of allegedly acting disrespectfully towards Chinese coaches during a training session. Zhanle made his comments in an interview with a Chinese broadcaster after the men’s 100m freestyle final in which he broke the world record. Chalmers labelled the allegation towards him 'a bit weird' and added: 'We had a laugh together at warm-down last night – but no issues from my end.' ‘Bit weird’: swimming rivalry heats up as Kyle Chalmers hits back at Chinese snub claim
