World leaders, among whom are Donald Trump, Vladimir Putin, Xi Jinping, Emmanuel Macron, Theresa May, Angela Merkel, Shinzo Abe and Justin Trudeau, have arrived in Argentina amidst high security measures.

A huge march and rally is expected to begin any minute as civil society, unions, workers, students and left parties have called on the people to join the protest which will be directed not only against the world leaders but also against current President Mauricio Macri.

The official agenda began at 10 am (Argentina time), with the arrival of heads of state and their delegations to the facilities of Costa Salguero.

Between 10.30 and 12 was the so called “Retreat of leaders", reserved to the G20 leaders, alone and without access to invited countries, international organizations or members of the committees.

Upon completion, the "family photo" had been taken as part of the official welcome.

At 12.30, Argentinian president, Mauricio Macri, said some opening words, and at 1 pm the first session of the summit begins and will include a "working lunch”.

Bilateral meetings among world leaders will take place during coffee breaks.

The Summit second session will take place after 3 pm, and at 6.30 the leaders will move to Teatro Colón. There they will see a performance that "will show the cultural diversity" of the country, according to the Argentine authorities. Then there will be a Gala Dinner in the Golden Hall of Columbus.

On Saturday the Summit will resume at 10 am.

The document with the conclusions of the Summit will be presented on Saturday afternoon and President Macri will say some closing words and will be followed by Prime Minister of Japan, Shinzo Abe, who will announce that the G20 will be taking place in the city of Osaka.

Argentinian president will then hold a press conference after which the other world delegations will talk to the press.
