A misunderstanding during a photograph opportunity at the G20 summit in Buenos Aires has seen US President Donald Trump walk off the stage, leaving Argentina's President Macri alone and confused on the global stage.
Trump said in exchange for the pause, China intends "to start purchasing agricultural product immediately" after saying in a late Sunday night tweet that Beijing "agreed to reduce and remove" a 40 percent tariff on US auto imports.
U.S. president Donald Trump and Chinese president Xi Jinping attend a working dinner after the G20 leaders summit in Buenos Aires, Argentina December 1, 2018.
Trump alluded - possibly inadvertently - to the "Great Leap Forward", Mao Zedong's disastrous campaign to rapidly industrialize China's agrarian economy, which historians believe led to the deaths of tens of millions of people in the Great Chinese Famine.
Of China's US$51 billion of vehicle imports in 2017, about US$13.5 billion came from North America, including sales of models made there by non-US manufacturers like BMW.
On Monday, China's ministry of foreign affairs said the Chinese and USA presidents had agreed to work towards removing all tariffs.
Global stock markets have jumped following the truce in the US-China trade war. "It goes down, certainly - if it happens, it goes down as one of the largest deals ever made", Mr. Trump told reporters aboard Air Force One as he returned from Argentina.
The agreement, hashed out over steak in the Argentine capital Buenos Aires, lowers the temperature in a conflict that has spooked world markets.
Stopping China’s Fentanyl River
The president also touted his personal relationship with Chinese President Xi, suggesting that it would be very productive in the future.
By agreeing to a 90-day ceasefire and freezing new White House-planned tariffs to allow for a series of talks to take place on a range of key issues, the early foundations of a deal have been laid.
That's precisely why China's statement highlighted Trump's apparent commitment to continue respecting the so-called one China policy - something not mentioned by the Americans.
Both sides will "immediately begin negotiations on structural changes" that Washington has been demanding for more than a decade.
Earlier this year, the Trump administration imposed new tariffs on almost $250 billion worth of Chinese goods, to force Beijing to end its unfair practices. The US spent 716 Billion Dollars this year.
However, he has faced fierce criticism from USA business groups, as the tariffs lead to reduced exports of crops such as soybeans, while raising costs for businesses that rely on Chinese imports. If they fail to reach an agreement by the end of this period, the tariffs will be increased to 25 percent from 10 percent.
Duties of 10 per cent now on most of those goods are set to rise on January 1 to a whopping 25 per cent if a deal isn't reached.
"China will still need to prepare for the worst scenario of a "decoupling" of the Chinese and American economies, in particular in the high-tech sector", Wang Yong, the director of the Center for International Political Economy at Peking University, said, adding that Beijing faced an increasingly hawkish Trump administration.
