Good morning, Quartz readers!
What to watch for today and over the weekend
China and the EU hold a timely summit in Brussels. Premier Li Keqiang and top EU officials will underscore their commitment to the Paris climate agreement after the US pullout. Also on the agenda: North Korean missile tests and global steel production.
Vladimir Putin chats with Western business execs. The Russian president is expected to drop in on a roundtable with the heads of BP, Boeing, and Total at the St. Petersburg Economic Forum.
Ireland may elect a gay prime minister. Leo Varadkar would be the youngest politician to become Taoiseach, and the first of ethnic minority heritage—his father is from India. Varadkar is up against housing minister Simon Coveney for the leadership of the Fine Gael party.
While you were sleeping
Donald Trump confirmed the US exit from the Paris Climate Agreement. The president said he would follow the accord’s withdrawal process, which will take a minimum of four years to complete. Trump vowed to renegotiate the deal to obtain better terms for the United States, but legal experts and the leaders of France, Germany, and Italy called that an impossibility.
Putin said Russian hackers might have interfered in the US election. In a shift from his previous denials, Putin said “patriotically minded” civilians could have carried out the cyberattacks that helped elect Trump.
Nigel Farage is a “person of interest” in the Trump-Russia investigation. The FBI wants to talk to the former Ukip leader because he has ties to both the Trump campaign and Wikileaks founder Julian Assange.
Walmart is asking employees to deliver packages on their way home from work. The US retail giant began a pilot program that tries to take advantage of its huge footprint as it competes with Amazon. It’s not clear how the employees would be compensated.
