Shortly after President Barack Obama set wheels down Saturday in Hangzhou, China his National Security Advisor Susan E. Rice, members of his entourage and the press corps tangled with Chinese officials both on the flight line and at the West Lake State House minutes before Obama’s meeting with Chinese President Xi Jingpin.

“A bit of chaos on the Tarmac,” read the feed from the White House press pool report by Wall Street Journal reporter Carol Lee.

Pool was brought under the wing of AF1 per usual but the scene was not per usual. There were no stairs to the top door to AF1, instead President Obama exited via the lower level stairs so pool could hardly see him, and only for a split second as he exited at 2:30 p.m. A member of the Chinese delegation was screaming at White House staff from the moment pool got onto the tarmac. He wanted he US press to leave. The Chinese had put up a blue rope under the wing so pool had to stand behind it. This man was demanding the pool, which was behind the blue rope, get away from the arrival scene altogether. At one point a White House official told him this was our president and our plane and the press wasn’t moving.

Lee wrote this assertion by the White House staffer did not go down well: “The man yelled, ‘This is our country.” He yelled at another White House official and got testy with Susan Rice and Ben Rhodes, seeming to try to block them from walking closer to the arrival scene after they lifted the blue rope and walked to the other side of it, nearer to POTUS.”

Obama was meeting with Xi and Ban Ki Moon, the secretary general of the United Nations, at the West Lake compound to formally accept the UN’s Paris Agreement on Climate Change, which is being trumpeted in the Chinese media as a huge diplomatic achievement for Xi.

The White House press corps has a rotating duty, where its members take turns writing up notes in situations when it is impracticable for the entire press corps to cover an event.

As the president walked down the red carpet, Lee wrote that the Chinese lined both sides of Obama’s path to his limousine, so that there was no way to take photographs or shoot video footage.

“Motorcade was rolling within minutes after that warm welcome,” Lee wrote.

Later, before the president arrived at the West Lake State House, a reporter asked Rice what happened at the airport and Rice replied, “They did things that weren’t anticipated,” according to the White House pool report.

The tension between White House staff and the Chinese officials erupted again at the meeting site along West Lake, when the White House advance team, staffers, and the press pool were stopped at the security gate to the compound, wrote William Wan, a reporter from The Washington Post, who took over the pool report duties from Lee.

At the same time as the confrontation at the gate, another group of the president’s advance staff, protocol and Secret Service officers who attempted to enter the compound through another entrance, “spent 15 mins in heated arguments with Chinese officials,” the pool report said.

The account continues as the arguments between Chinese officials and White House staff nearly broke out into fisticuffs:

US officials could be heard arguing in Chinese with Chinese security officials over how many Americans could be allowed to go through security at a time. How many people the White House were allowed to be in building before the president’s arrival. Which US officials were on which list in a folder with a thick pile of name lists.

“The president is arriving here in an hour,” one White House staffer was overheard saying in exasperation.

As the disagreement escalated, a Chinese official assisting the Americans grew angered by how guards were treating the White House staff and began yelling, nearly coming to blows with one of the Chinese security officials.

“You don’t push people. No one gave you the right to touch or push anyone around,” he yelled in Chinese at one of the Chinese security officials. Another Chinese official trying to help US officials stepped between the two who were arguing once the security official began approaching, looking like he was going to throw a punch.

“Calm down please. Calm down,” pleaded a White House official.

“Stop, please,” said a foreign ministry official in Chinese. “There are reporters here.”

But, hold on, sports fans. The action was not over yet.

As soon as the White House communications staff entered the state house, the arguments started up again, when the White House press officers lobbied for the traveling press corps to gain entry, the pool report said. “You are only allowed 10,” said a Chinese official.

Apparently, 10 was not the correct answer. “That’s not right,” the pool report quotes the White House press official. In fact, two reporters who had traveled with the president were left outside.

The shouting did not abate, the report said.

Twenty minutes before Obama’s arrival, U.S. press officers were still arguing in the room where the two presidents would soon be meeting along with Ban Ki Moon to talk of their cooperation. As U.S. official a pleaded for two U.S. journalists left outside to be allowed to stand in the back of the room. “There’s space. They are print reporters. They would just be just standing,” said one White House press officer.

It was a fight they did not win.

Later, Wan was able to report, “Just to make sure: Last two reporters mentioned in precious pool report got in. (Thanks to our valiant press handlers)”
