In an interview Chang pronounced support for President Trump's consideration of completely decoupling the U.S. economy from China, calling the move "absolutely a good idea."
"China is configuring its military to kill Americans," Chang told "Bill Hemmer Reports."
"We shouldn’t be enriching a hostile regime with our trade and with our investment. I believe that decoupling is what we absolutely have to do, especially this year."
Chang's statements follow a recent Pentagon report assuming that China's plan is to double its nuclear warheads reservoir in this decade -- including those made for ballistic missiles and that can reach the U.S. The report adds a time clock to Trump's call, Chang said.
"[President] Xi Jinping has been talking increasingly about this notion that China has a mandate of heaven to rule the world," Chang explained. "They [believe that they] not only have the right to do it, they have the obligation to do it."
"He’s become very specific about this in public and so have his officials, which means that they are trying to change the international system, not to compete within it," Chang said.
"The Coming Collapse of China" author cautioned that the Chinese government is putting effort fast to counter a "closing window of opportunity'' because of the problems in the economy, in the environment, and demography.
"I think China believes it needs to move fast and that means we’re going to see problems not in the 2030s, we’re going to see problems now," he emphasized.
Trump suggested the possibility of severing ties with the Communist country during an interview with Steve Hilton, a prominent Trump supporter, last month.
"There has been no country that has ripped us off more than China...," Trump said at the time. "We lose billions, hundreds of billions of dollars. We get nothing from China. Yes, we get some goods that we could produce ourselves…. [But] we get nothing. All we do is lose money."
As far as his landmark trade deal signed by both countries in January, Trump said the accord is "longer the same to me" after their "handling" of the coronavirus and that "if they don't treat us right," he would "certainly" sever ties with Beijing.
"President Donald Trump is committed to making sure that we hold China accountable for this virus now destroying hundreds of thousands of lives all across the world and billions of dollars in wealth. We will hold the Chinese Communist Party accountable for that" Michael R. Pompeo, Secretary of State Department.
