1. The face of Nike: Nike is throwing its weight behind one of the most polarizing figures in America: former San Francisco 49ers quarterback Colin Kaepernick.

Kaepernick will be one of the faces of Nike's 30th anniversary commemoration of its iconic "Just Do It" slogan.

The quarterback has not played in the NFL since the 2016 season, when he began kneeling during the national anthem to protest police brutality against African-Americans and other racial injustices.

Nike (NKE) is gambling that its customers support his protest, or at least that enough of them do. The company is also betting its brand can withstand criticism from conservative corners, including the White House.

2. Argentina meets the IMF: Argentina is getting rid of half of its government ministries and hiking taxes on exports as it grapples with the collapse of its currency.

President Mauricio Macri announced a series of austerity measures on Monday, the day before his government is due to meet officials from the International Monetary Fund.

Argentina is trying to speed up the release of cash from a $50 billion bailout plan.

The Argentine peso has cratered this year with investors worried about the government's ability to pay its debts. It has lost more than 50% of its value against the US dollar.

Last week, the central bank increased interest rates to 60% in an attempt to stabilize the peso.

JD.com (JD) has said Liu was falsely accused while on a business trip.

JD.com is China's second-largest online shopping site after Alibaba (BABA). It's listed on the Nasdaq.
