U.S. President Donald Trump arrives to speak to the media at a NATO news conference in Brussels, Belgium.

The officials sketched a rough outline of Trump's schedule for meetings with world leaders over the course of the event, which takes place Tuesday and Wednesday, including:

"Russia has shown a consistent disregard for the sovereignty and territorial integrity of its neighbors. Certainly that's something that will be discussed at the leader summit," the official said.

The Trump administration also expects that NATO's relationship with Russia "will certainly come up," an official said.

"There are continuing challenges that NATO needs to face, China above all," one official said in a conference call.

Senior Trump administration officials told reporters Friday that the American president is also expected to stress the ongoing challenges that NATO and the international community face from China and Russia, two nations that have become inextricably tangled up in Trump's domestic political battles.

WASHINGTON — President Donald Trump is set to meet with representatives of at least a dozen nations, including Germany, France, Italy and Denmark, at the North Atlantic Treaty Organization's 70th anniversary meeting in London next week.

The officials noted that the administration is working to lock down additional bilateral meetings that may be announced at a later date.

The NATO meeting is scheduled to take place in London just days after a man was killed near London Bridge in an incident that authorities there are treating as a terrorist attack.

The Trump administration officials also warned of China's pursuit of greater global influence and highlighted the risks of 5G technology.

The U.S. will "absolutely" bring up 5G at the NATO meeting, an official said.

"This has been a major push of ours. We are absolutely going to insist that our NATO allies use trusted and reliable partners, providers in their 5G networks. This is not something where they want to allow the Chinese Communist Party to be able to siphon off their data or entry into their networks at all. So this is a very, very high priority for us, and the president is going to reiterate that message," the official said.

U.S. officials have long complained that Chinese intellectual property theft has cost the economy billions of dollars in revenue and thousands of jobs and that it threatens national security.

China maintains that it does not engage in intellectual property theft. The issue is central to the repeated attempts between the two economic superpowers to strike a trade deal that will also address the U.S. trade deficit with China and so-called forced technology transfers. The first "phase" of a deal was announced in principle in mid-October, but it has yet to be formalized on paper more than a month later.

Last year, the Pentagon halted sales of Huawei and ZTE mobile phones and modems on U.S. military bases around the world due to potential security risks.

"These devices may pose an unacceptable risk to the department's personnel and mission," wrote Pentagon spokesman Lt. Col. Dave Eastburn in a previous statement to CNBC.

Since 2012, the U.S. government has warned against using Huawei equipment and component parts. The company has been effectively banned since that time, and Trump's executive order in May made the recommendations official.

"U.S. government systems should not include Huawei or ZTE equipment," a 2012 report by the Permanent Select Committee on Intelligence said. "Similarly, government contractors, particularly those working on contracts for sensitive U.S. system, should exclude ZTE or Huawei equipment from their systems."
