When president Barack Obama arrived in China on Saturday, typical pleasantries were spoiled slightly after a Chinese official began shouting at U.S. White House staff.

Chinese authorities have imposed extremely tight security precautions for the G20 summit.

Not even U.S. National Security Adviser Susan Rice and the White House press corps proved exempt when Air Force One landed in host city Hangzhou.

President Barack Obama arrived in China on Saturday for his final G20 summit as president, but his initial landing was marred by tension between Chinese officials and White House staffers

Chinese authorities have imposed extremely tight security precautions for the G20 summit, which cause tempers to flare on the tarmac

U.S. National Security Adviser Susan Rice and senior White House staffer Ben Rhodes were blocked from getting close to the president until Secret Service stepped in and escorted them

When Obama travels, the reporters accompanying are brought under the wing of the Boeing 747 to watch him come down the aircraft stairs.

On Saturday they were penned off behind a blue rope installed by Chinese security.

But that was not far away enough for the Chinese personnel, one of whom screamed at White House staff, demanding the U.S. press leave the scene.

A female White House official (pictured), handbag over her arm, told him that it was an American plane and the U.S. president

'This is our country!' the Chinese official, in a dark suit, shouted at her in English. 'This is our airport!'

A female White House official, handbag over her arm, told him that it was an American plane and the U.S. president.

'This is our country!' the Chinese official, in a dark suit, shouted at her in English. 'This is our airport!'

When U.S. National Security Adviser Susan Rice and senior White House staffer Ben Rhodes tried to get closer to the president, lifting up the blue rope and walking under it, the official turned his ire on Rice, trying to block her progress.

As they exchanged angry words her Secret Service agent stepped in to usher her past him.

After the tense landing, Obama was on his way to the G20 summit - his last as president of the United States

Moments after the heated argument the U.S. president's motorcade was rolling away.

Hangzhou is a city of nine million people but it has been denuded of around a quarter of its population for the event.

Factories have been closed to ensure blue skies, potential troublemakers detained, and the wide boulevards of a city lauded by Venetian traveler Marco Polo are empty.

'They did things that weren't anticipated,' Rice told reporters later.

Obama is attending the G20 summit - his last as president, this week.

At the international forum of nation leaders in Hangzhou, China and the U.S. ratified the Paris Agreement for both countries.

The Paris Agreement, which is part of the UN's 2015 Convention on Climate Change, is an arrangement to begin greenhouse gases emissions mitigation, adaptation and finance in the year 2020.

Last year 195 countries negotiated the language of the agreement and came to a consensus that was agreed upon by all the nations.
