The Biden administration plans to issue an executive order that will restrict U.S. investment in China in high-tech sectors, according to U.S. media reports. Artificial intelligence, semiconductors and quantum computing will be targeted in a bid to curb China's progress in critical technologies. It comes as Australia and the U.S. have just discussed ways to deepen their military alliance in the Indo-Pacific at the 33rd Australia–U.S. Ministerial Consultations last month. China recently lifted anti-dumping and countervailing duties on imported Australian barley, a sign of improved ties. Are we seeing diverging interests between U.S. and Australia, an alliance that has been rock solid dating back to the World War days? How serious of an impact will these bans and restrictions have on China's high-tech development?
