"For decades we allowed the CCP free and unfettered access to USA institutions and businesses while these same privileges were never extended freely to U.S. citizens in China", a State Department spokesperson said in a statement.
Director of National Intelligence John Ratcliffe beseeched any incoming Biden administration on Thursday to "get past politicizing intelligence" and admit China, not Russian Federation, is the greatest security the United States faces.
"All of the threat streams that we have, from all aspects, militarily, economically, supply chain issues, foreign investment, technologically, cyber issues, cyber warfare, 5G, telecommunications - China is in all of those and they are the only country to be in that space and the only country that threatens America supremacy".
Some damage to Sino-US ties are "beyond repair" amid a new wave of Trump administration measures to counter China, Chinese state media warned.
The Director of National Intelligence said China had replaced Russian Federation and counter-terrorism as the main focus of U.S. intelligence activities.
The U.S. State Department on Thursday tightened travel restrictions on members of the party and their families.
The two countries have also restricted journalist visas, with Washington earlier this year limiting the number of Chinese nationals from state-run news outlets.
Foreign ministry spokesperson Hua Chunying said China would "make representations" to the US over its decision to limit such people to one-month, single-entry visas.
He said the strategy was for Chinese entities to steal American companies' intellectual property, copy it and then supplant U.S. companies in the global marketplace.
Ratcliffe said he has personally briefed members of Congress about how China is using intermediaries to lawmakers in an attempt to influence legislation.
Sino-US relations have hit rock bottom after outgoing President Trump's disputes with Beijing over issues ranging from trade to Hong Kong to the pandemic.
Earlier this year the U.S. ordered a Chinese consulate in Houston to close over economic espionage concerns - Beijing responded by ordering the USA to close its consulate in the city of Chengdu.
"This is an escalation of their political oppression towards China and China is firmly opposed to that", she said. However, it said earlier reports that the U.S. was considering travel restrictions showed the Trump administration's "hatred and abnormal mindset towards the Communist Party".
It also banned cotton imports from a quasi-military organisation in Xinjiang it said uses forced labour of detained Muslims, while the House passed a law to kick Chinese firms off U.S. stock exchanges if they do not comply with auditing rules.
China's ambassador to the United States became the latest of the Asian nation's senior officials to signal a desire to reset the increasingly confrontational relationship as president-elect Joe Biden prepares to take office in January.
Congress and the Trump administration have sought increasingly to curb the US market access of Chinese companies that do not comply with rules faced by American rivals, even if that means antagonizing Wall Street.
