Senior government delegations led by U.S. President Donald Trump and Chinese President Xi Jinping were initially tight-lipped about the results of their two-day meeting last week at Trump's Mar-a-Lago resort in Florida.

Cabinet members like Treasury Secretary Steven Mnuchin, Commerce Secretary Wilbur Ross and Secretary of State Rex Tillerson initially agreed to speak to reporters off-camera, and a White House pool report indicated some sort of 100-day trade plan had been ironed out and that China had agreed to increase cooperation in reining in North Korean military provocation.

But questions remained as to just what that trade plan would entail and, more broadly, what specific progress Trump and Xi had made over the course of their two days in Florida.

And days later, few other details have emerged suggesting anything concrete was knocked out in Mar-a-Lago.

"To my understanding, as of now, there is yet to be any black-and-white fact sheet or communique or the like to have come out of this meeting," Nate Olson, director of the Stimson Center's Trade21 initiative, said at a Stimson Center event Monday.

During a debriefing event hosted by Olson's policy think tank, analysts speculated that the public is still in the dark over the U.S.-China summit in part because the Trump administration is shaping up to be less of an open book than the government was under President Barack Obama.

Some also wondered if the lack of information was simply caused by the lack of substantive news to share.

"I was surprised. I think we've all been spoiled by the Obama administration, which produced endless documents for ... these things," William Reinsch, a distinguished fellow at the Stimson Center and the former president of the National Foreign Trade Council, said Monday at an event hosted by the Stimson Center. "It just may well be that this administration is not going to do it that way. The more cynical view would be there is no fact sheet because there are no facts, and there's nothing to come out with."

Many analysts expected some degree of secrecy to shroud Trump's and Xi's conversations, in part because of China's tight control of domestic media and in part because Trump in recent weeks has repeatedly indicated he doesn't "have to tell" the press what he's doing behind closed doors.

But few expected such a degree of radio silence.

"President Trump has been saying that he's going to be negotiating with China to have a grand bargain and strike deals," said Yun Sun, a senior associate at the center's East Asia program. "He's favoring negotiation and his ability to strike deals, so when people don't see those concrete deliverables, there is a question that people ask."

The White House did eventually end up distributing a read-out of Mnuchin's, Ross's and Tillerson's comments, and press secretary Sean Spicer's office hours later issued a statement describing the meetings as "positive and productive."

But even those added details and quotes didn't offer up much short-term gratification. And in explaining the U.S.-China 100-day trade plan during a press briefing Monday, Spicer said "the plan was to put together a plan, and there's a lot of pieces that both sides would like to see in there."

"This is an initial working plan that they're going to try to hammer out what that 100 days looks like," Spicer said. "It is something that the counterparts are now going to continue to flesh out."

In other words, the goal at the end of the 100-day plan appears to be a moving target that hasn't been pinned down yet.

"They haven't really defined an acceptable outcome either. So it's not clear what will be a satisfactory outcome in terms of the administration's point of view," Reinsch said.

Still, the general consensus at Monday's event seemed to be that Xi's and Trump's meeting was far from fruitless. Reinsch noted expectations were low for any kind of overarching policy shift to come from the first meeting between the leaders of the world's largest economies and that the gathering was expected to be more focused on relationship building. He ultimately said it's important not to "move the goalposts here."

"I think both sides were clear in stating that the primary goal of the summit was to establish a good working relationship … and to establish a framework for future discussion," he said. "They didn't yell at each other as far as we know, and they presumably had frank exchanges."

Additionally, the summit did appear to result in at least some short-term news. The Financial Times over the weekend reported that Beijing had offered to make it easier for U.S. financial services investments and beef exports to make their ways into the Chinese market, citing unnamed Chinese and American officials. Spicer appeared to confirm that offer during his Monday briefing.

Reinsch indicated the beef trade tweaks could mean "a lot of money" for U.S. ranchers but that it'll be "difficult" to say "how meaningful" the financial services adjustments will be without more public information.

"The reality of doing business in China is that there are a whole bunch of ways you can limit access to the market," he said, noting that reducing barriers in one area or another doesn't necessarily guarantee meaningful progress.

Still, he said there's "not much" to talk about in the way of what the 100-day plan will mean and what else was actually accomplished at the summit, calling the public comments "extremely paltry." He said it's "traditional, particularly with Chinese summits, for there to be … concrete deliverables."
