This time China is accused of a major cyber-attack.
The Trump administration has been roiled by the FBI Special Counsel investigation into alleged Russian interference in the 2016 election, and intelligence officials have warned about the danger of Russian meddling in the midterms.
"It is very ridiculous for the United States side to stigmatise its normal exchanges and cooperation with China as China interfering in its internal affairs and elections", Ms Hua said. A recent intelligence report said China uses joint ventures to try to acquire technical know-how, seeks partnerships with US government labs to learn about specific technology and information about running such facilities, and uses front companies to hide the hand of the Chinese government and acquire technology under USA export controls.
Chris Johnson, a former Central Intelligence Agency analyst and China expert now at the Center for Strategic and International Studies think tank in Washington, said Pence's speech appeared aimed at building a narrative that a vote for the Democrats would be vote for China.
The Trump administration also asserted Thursday that Chinese "economic aggression" has helped undermine the global competitiveness of defense-oriented USA industries.
China has previously denied Trump's accusation.
While Pence declared that behavior of Russian Federation "pales in comparison to what China is doing across this country", he only cited vague internal declarations by USA intelligence agencies and then pointed to an advertisement, purchased by the state-run China Daily newspaper, that was placed in the Des Moines Register that criticized the Trump administration's trade war tactics.
Pence alleged China was waging a sophisticated effort to sway the November 6 elections against Trump's Republican Party in retaliation for his trade policies against Beijing and vowed to continue to expose Beijing's "malign influence and interference". "To my mind there's nothing in that speech that rises to the level of 2016 Russian active measures".
Pence also said more USA companies should think twice before entering the Chinese market if it means turning over their intellectual property.
The intervention by the vice president marks a significant broadening in the rhetoric used by the Trump administration to confront China, linking issues around military, trade and domestic politics. "For example, Google should immediately end development of the "Dragonfly" app that will strengthen Communist Party censorship and compromise the privacy of Chinese customers".
"Beijing is employing a whole-of-government approach, using political, economic and military tools, as well as propaganda, to advance its influence and benefit its interests in the United States", Pence said. "A Chinese naval vessel came within 45 yards of the USS Decatur as it conducted freedom-of-navigation operations in the South China Sea, forcing our ship to quickly manoeuvre to avoid collision".
-Beijing compelled Delta Airlines to publicly apologize for not calling Taiwan a "province of China" on its website, he said.
Pence also denounced China's manoeuvres in the South China Sea, its oppression of Christians, Muslims and other religious believers, and Chinese President Xi Jinping's signature infrastructure and foreign policy initiative. US officials have said they are considering targeted sanctions over alleged human rights abuses.
