I will speak to the reunion OF G20, this last 17th and 18th March based in Baden-Baden, in Germany, during two days.
The G20 is an economic forum created in1999 after the Asian financial crisis.
It brings together 19 states, plus the European Union.
It seeks to foster international cooperation in industrialized and emerging countries with a significant economic impact.
It brings together ministers, heads of central banks and heads of state regularly.
Washington has begun to question the global doctrine of free trade and multilateralism, as well as the fight against climate change.
Multilateralism is a system of international relations which favors negotiations, reciprocal commitments, cooperation, agreements between more than two countries, with the aim of establishing common rules.
Finance ministers from the world's biggest economies have dropped an anti-protectionist commitment after opposition from the US.
G20 ministers left the two-day meeting without renewing their long-standing pledge to bolster free trade.
But since then, President Donald Trump has taken office, and is aggressively pursuing an "America First" policy.
His policies include penalties for companies which manufacture their products abroad.
Financial officials from the world's biggest economies have dropped from a joint statement any mention of financing action on climate change, reportedly following pressure from the US and Saudi Arabia.
Protectionism can include border tariffs and rules that favour a country's businesses over those in another economy.
The text, fiercely negotiated by all countries, no longer mentions protectionism or the Paris Climate Accord, thus approaching the US government's positions of Donald Trump, climate-skeptical and hostile to free trade, exchange.
Faced with the impasse of the finance ministers on trade and climate, the responsibility to find a solution, risks returning to the heads of state and government that are due to meet in July in Hamburg.
