Many of the world's most prominent leaders gathered at the G20 summit in Buenos Aires on Friday, including President Trump, Russian President Vladimir Putin and Saudi Crown Prince Mohammed bin Salman (MBS) — whose interactions have remained firmly in the headlines over recent weeks.

Why it matters: The G20 comes amid multiple international controversies, including Trump's continued pledge to work with Saudi Arabia despite questions surrounding MBS' involvement in the murder of journalist Jamal Khashoggi as well as Trump's decision to cancel a one-on-one meeting with Putin citing ongoing conflict in Ukraine.

This friendly handshake between Putin and MBS rocked the Twittersphere:

Hong Kong media tycoon Jimmy Lai arrested under national security law

Hong Kong pro-democracy activist Jimmy Lai has been arrested for "collusion with foreign powers," said Mark Simon, an executive at the tycoon's media firm Next Digital Monday morning local time.

Why it matters: He was arrested under the new national security law that gives Beijing more powers over the former British colony. Lai is the most prominent person arrested under the law, which prompted the U.S. to sanction Chinese officials, including Hong Kong leader Carrie Lam, over Beijing's efforts to strip the territory of its autonomy.

New York Gov. Andrew Cuomo (D) announced Sunday 515 people, or 0.78% of those tested, returned a positive reading for COVID-19 the previous day.

Why it matters: It's the lowest single-day positive rate since the start of the pandemic. It's another sign that the state that was once a global coronavirus epicenter is curbing the spread of the virus. "Our daily numbers remain low and steady, despite increasing infection rates across the country, and even in our region," Cuomo said in a statement. "But we must not become complacent: Everyone should continue to wear their masks and socially distance."
