(CNSNews.com) - China will be one of the main topics on Wednesday when the Senate intelligence committee holds a hearing on worldwide threats to the United States.

The witnesses scheduled to testify include Director of National Intelligence Avril Haines, CIA Director William Burns, FBI Director Christopher Wray, National Security Agency Director Paul Nakasone and Defense Intelligence Agency Director Scott Berrier.

"We have never had a potential adversary like China," Committee Chairman Mark Warner (D-Va.) told "Fox News Sunday."

Warner said he is about to introduce a bipartisan bill that would ban some foreign technology coming into this country, including TikTok.

"This week, I've got a broad bipartisan bill that I'm launching with my friend John Thune, who will be the Republican lead, where we're going to say, in terms of foreign technology coming into America, we've got to have a systemic approach to make sure we can ban or prohibit it when necessary...

...That means TikTok. It's one of the potentials. "Listen, TikTok is not only -- you have 100 million Americans on TikTok 90 minutes a day. Even you guys would like that kind of return, 90 minutes a day.

"They are taking data from Americans, not keeping it safe. But what worries me more with TikTok is that this can be a propaganda tool to basically -- the kind of videos you see would promote ideological issues.

"If you look at what TikTok chose to the Chinese kids, which is all about science and engineering, versus what our kids see, there's a radical difference."

Warner said the U.S. miscalculated by expanding trade with China, following China's accession to the World Trade Organization in 1999:

"I think for a long time, conventional wisdom was, the more you bring China into the world order, the more they're going to change.

"And that assumption was just plain wrong. China even changed their laws in 2016 to make it explicitly clear that every company in China, their first obligation is to the Communist Party.

"So, we have never had a potential adversary like China. Soviet Union, Russia, was a military or ideological. China is investing in economic areas. They have $500 billion intellectual property theft. And we are competition not just on a national security basis but on a -- on the technology basis.

"That's why national security now includes telecommunications, satellites, artificial intelligence, quantum computing. Each of these domains, we've got to make the kind of investments to stay ahead.

"And I think we're starting that in a bipartisan way. We did the CHIPS bill, of trying to bring semiconductor manufacturing back. We've kicked Huawei out of our telecom systems."

Other U.S. concerns about China include the apparent COVID lab leak in Wuhan and China's suspected support for Russia's war in Ukraine.
