The two-day 13th G20 Leaders' Summit has wrapped up with a joint declaration in the Argentine capital Buenos Aires.

The members have reached consensus on keeping strong global economic growth while improving a rules-based international order. The group stressed the importance of multilateral trading system in global trade, calling for reforms to the World Trade Organization. They also said transformative technologies are expected to bring immense economic opportunities. Regarding climate change, the United States stuck to its holdout stance, while all other G20 members reaffirmed the Paris Agreement is irreversible. CGTN's Joel Richards has the details.

It began with smiles. But under the surface of this year's G20 Leaders' summit were simmering geopolitical tensions, from a dispute over a vision for the world economy to a dispute over the urgency with which climate change must be confronted.

Host Argentina hoped this summit would conclude with a broad consensus on the global economy. The final communique mentions a rules-based international order, while also agreeing on reforming the World Trade Organization.

On Saturday afternoon, Argentina's President Mauricio Macri said there was an agreement on a number of issues.

MAURICIO MACRI ARGENTINE PRESIDENT "The communique clearly shows that we all agree on trade growing among countries. What it looks at with the restructuring of the WTO is that it is on fair terms."

The countries that signed the Paris Agreement stated their commitment to tackling climate change. But the United States confirmed its decision to withdraw from the pact.

These two days in Buenos Aires have been defined by bilateral meetings and the much anticipated get together between the presidents of China and the U.S.. Despite the charm offensive by the host nation, even Argentina admits the final result falls short of what it had hoped for.

JOEL RICHARDS BUENOS AIRES "This was the first G20 Leaders' summit held in South America. Argentina had hoped a consensus on a series of issues, but the final communique delivers a compromise that likely satisfies few of the countries here. Joel Richards, CGTN, Buenos Aires."
