Indispensable as our biggest trading partner, unmistakable as the rising military superpower, China is a giant challenge for our government. Few have spent longer studying that challenge than Geoff Raby. Australia's former Ambassador in Beijing sits down with 'The Issue' just as Prime Minister Albanese travels to China to meet President Xi Jinping. What must Albanese achieve in the meeting? How great is the military threat to our region? How does the Trump presidency in the United States change the equation? Raby addresses these issues, his time getting to know China's President and even his work in China with Kevin Rudd as he chats with The Issue.
