"I believe our world is at a crossroads and what we do next week not only as governments but as business leaders, media, influencers and ordinary citizens matters enormously", Mrs Clinton said on Friday.
Speaking in Melbourne, Clinton asked in jest that the audience "forget that I got three million more votes - it's over", in reference to her popular vote win, as compared with her Electoral College loss.
"What we're seeing now is a desire by China to extend its influence and project its power".
I think we should take Hillary Clinton's alarmist remarks about China's takeover motives with a rock of salt - especially now that US President Donald Trump has made this backward step of withdrawing his country from the Iran nuclear deal, and also threatened sanctions on countries which continue to trade with Iran. "First throughout Asia - then, throughout the world", Clinton said.
In 2017 he said: "This Russia thing with Trump and Russia is a made-up story". "I pointed out that you can't drown a witch", noted Gillard, who served as prime minister from 2010 to 2013.
She said Russian President Vladimir Putin's authoritarianism was "rippling out from the Kremlin" and emboldening right-wing nationalists, separatists, racists, and neo Nazis across Europe and beyond.
She said: "Whether it's Russian Federation in a secret way interfering with our election and producing more than 3,500 ads to try and confuse our electorate to try to damage me, to the Chinese looking to influence policy, we should say no".
'This is an urgent problem and one we must confront immediately and together, ' she declared.
But Ms Clinton warns that 'It's not just happening in the United States.
In December, Australia's Prime Minister proposed banning foreign political donations, citing "disturbing reports about Chinese influence". According to data from the Lowy Institute, China spent $1.7 billion in aid and concessional loans to fund 218 projects in the Pacific Islands between 2006-2016.
