Sky News host Catherine McGregor says “we need to make the cost of going to war over Taiwan intolerable” for China.
This comes as nearly 150 Chinese warplanes have breached Taiwan’s air defence zone since last Friday.
Ms McGregor said “we’re on the precipice” of war but “we can avoid going over the brink”.
“And it’s by actions like what Tony Abbott’s doing, and this tripartite agreement with the United States and the UK,” she told Sky News host Alan Jones.
“We’ve got to enhance capacity; we’ve got to show resolve and we’ve got to put pressure on Xi internally.”
