Hard Numbers: The world economy hasn't looked this glum since when?

14: At least 14 police were killed and three injured when drug cartel gunmen ambushed a convoy in Michoacán state in western Mexico. The attack highlights the difficulties facing Mexican President Andrés Manuel López Obrador, whose first year at the helm may end with a record number of killings in his country.

200: Two-hundred Hong Kong protestors have been arrested since the weekend, when a spike in violence and vandalism swept the city: unrest has been rising since the government invoked colonial-era emergency powers several weeks ago. More than 2,300 demonstrators have been arrested since June.

⅓: At least one-third of all food produced for human consumption globally is wasted or lost every year, according to a United Nations report. While enough food is produced to feed everyone on the planet, the hunger rate is rising: 820 million people around the world are "chronically undernourished," the UN says.

0.8: Global economic growth this year will slow to its weakest level since the 2008 global financial crisis, the International Monetary Fund predicts in its latest forecast. The US-China trade war is a big reason why: the tariff spat between the world's two largest economies could knock 0.8% off global GDP by 2020.

In an interview with GZERO World host Ian Bremmer, Hong Kong lawmaker Dennis Kwok, an outspoken pro-democracy advocate, expresses his concerns that the current "draconian" laws China's leadership is forcing upon his city has expedited the end of the "one country, two systems" policy established in 1997.

For 30 years, citizens of Hong Kong have gathered in Victoria Park on the evening of June 4 to honor the peaceful protesters massacred in Beijing's Tiananmen Square on that date in 1989. It has been the only public Tiananmen commemoration permitted on Chinese soil.

This year, the park was surrounded by barricades to keep people out. The officially stated reason for the shut-down? Crowds spread coronavirus. (In this city of more than 7 million, COVID has so far killed four people.)
