Warwick Powell, adjunct professor at Queensland University of Technology, refutes U.S. Treasury claims that China's export controls are "hurting the global economy," pointing instead to America's "bad faith" and reliance on rare earth materials for the production of weapons. He argues that China's refusal to supply materials for weapons targeting China reflects rational national security demand – not economic weakness. He also points out the U.S. dislikes that its "military-industrial complex and principal tools of global domination" are being challenged by someone saying "enough is enough."
