Good morning, Quartz readers! What to watch for today It's 30 years since the massacre of Tiananmen Square's young idealists. Student protests calling for a freer China, which began upon the death of a loved Communist leader in April 1989, ended in bloodshed on June 4 as the People's Liberation Army fired upon China's own people. Many of the former student protesters now live in the US; others emerged from prison into a China where many have accepted an all-powerful state in exchange for prosperity. A Chinese general in recent days defended the crackdown and a state tabloid called it "a vaccination" against political turmoil. Despite deeper online censorship around the anniversary, people find ways to signal that they remember—and Hong Kong will hold its annual vigil tonight. Donald Trump warns the UK over Huawei. Getting Britain to back away from the controversial Chinese telecom company is top of the agenda for the US president as he meets with outgoing prime minister Theresa May. The US earlier this month blacklisted the firm from US supply chains over national security concerns.

The Muslim world gears up for Eid feasting. The holy month of Ramadan, which began in early May, ends with the fast-breaking festival of Eid al-Fitr once the new moon is sighted. While a few began celebrating yesterday, many more will mark Eid today, and yet others will celebrate Eid from tomorrow. While you were sleeping The shadow of regulators darkened over Big Tech. Google, Amazon, Facebook, and Apple stocks all slid on news that regulators are divvying up responsibility for potential probes. The US Department of Justice will be handling any investigations that arise into antitrust allegations against Google and Apple, while the Federal Trade Commission has oversight for Amazon and Facebook. Meanwhile, the House Judiciary Committee is looking at whether antitrust rules have kept up with the times. Sudan's army backtracked on pledges to protesters. After a deadly raid by the military on protesters in Khartoum yesterday, the transitional military council—set up in April after longtime ruler Omar al-Bashir was ousted—said it was scrapping all agreements with the demonstrators. It said it would hold elections in nine months.
Australia cut its interest rate to a record low of 1.25%. The Reserve Bank of Australia's first rate cut in three years aims to counteract sluggish unemployment and wages.
Apple announced a redesigned Mac Pro. The company ditched its wastebasket-like 2013 design for a new look reminiscent of a giant cheese grater.

Italy's prime minister threatened to quit over infighting. Giuseppe Conte said he's fed up by bickering between the ruling League and its populist partner the Five Star Movement, as he tries to resolve a spat with the European Union over a budget that defies the bloc's fiscal rules. Membership Fashion has historically been defined by its great houses and the gowns, suits, and handbags they crafted. These days, however, it's all about sneakers. The transformation of what used to be gym equipment into a leading artifact of high fashion says a lot about how we've changed as a culture. Delving into sneakers' rapid ascendance is Marc Bain, Quartz's fashion reporter, starting with a state of play memo laying out the growth of the sneaker industry both financially and culturally.
