We’re covering an expanding global trade war, China’s retaliation over U.S. support of Hong Kong and an intimate look at an American high school torn apart by the opioid crisis. | | By Melina Delkic | | A worker moving a roll of aluminium cable at a plant in Barcarena, Brazil. Last week the country's currency fell to a record low against the dollar. Paulo Fridman/Bloomberg | | The currencies of Brazil and Argentina have both fallen sharply, but economists and government officials rejected the idea that the two countries were manipulating their currencies. | | Big picture: The tariffs suggest Mr. Trump has not abandoned his confrontational approach to trade. | | Context: The currency movements have made Brazilian and Argentine goods cheaper to buy abroad. China, in the face of Mr. Trump’s tariffs, has also shifted its purchasing of agricultural goods to those countries, which has rankled American officials. | | The U.S. aircraft carrier Ronald Reagan was allowed to visit Hong Kong two weeks ago as China sought to ease tensions. Kin Cheung/Associated Press | | The largely symbolic move was retaliation for a newly enacted U.S. law supporting anti-government protests in the semiautonomous territory. | | Details: A spokeswoman for the Chinese Foreign Ministry said sanctions would be imposed on Human Rights Watch, the National Endowment for Democracy and other organizations, and accused them of instigating violence. | | Reality: It was unclear what effect the sanctions would have, as most of the organizations listed do not have offices in mainland China. The measures suggested that Beijing did not want the dispute over Hong Kong to spill over into its trade negotiations. | | Huawei's chief financial officer, Meng Wanzhou, arriving at court in Vancouver in October. Darryl Dyck/The Canadian Press, via Associated Press | | On the first anniversary of her arrest on fraud charges, the Huawei technology executive Meng Wanzhou described her detention in Vancouver as having “moments of fear, pain, disappointment, helplessness, torment, and struggle.” | | In a letter, published on Huawei’s website on Sunday, Ms. Meng described her daily life since being freed on bail; she is still not allowed to leave the city. “Right now, time seems to pass slowly,” she wrote. | | Reminder: Ms. Meng is accused of deceiving four banks to enable Huawei to evade American sanctions against Iran. | | Global context: The arrest of Ms. Meng thrust Canada into the center of a U.S.-China diplomatic battle. China has imposed new trade restrictions against Canada and detained two Canadians on espionage charges. | | The graduating class of 2000 started at an Ohio high school the same year Purdue Pharma introduced OxyContin. In a few years, opioid painkillers were everywhere — in classrooms, school bathrooms and parties. | | The Times talked to dozens of members of the class to understand the scope of the American opioid crisis. Most of their lives were touched by addiction, and some of their classmates are among the more than 400,000 Americans who have died from opioid overdoses. | | PAID POST: A MESSAGE FROM CAMPAIGN MONITOR | TEST: Email Marketing 101: Never Sacrifice Beauty for Simplicity | A drag-and-drop email builder, a gallery of templates and turnkey designs, personalized customer journeys, and engagement segments.

Critics have denounced the move as a diversion to distract from the kingdom’s human rights record. | | Lauryn Ishak for The New York Times | | London victims: Saskia Jones and Jack Merritt were killed by a former alumnus of the prison education program they worked with in an apparent terrorist attack. | | What we’re watching: This BBC Breakfast video, in which the head of Fishmonger’s Hall, where the London Bridge stabbing attack began, recounts the bravery of his staff. “Amazing,” writes our reporter Sarah Lyall, who lived in London for years. | | Julia Gartland for The New York Times. Food Stylist: LIza Jernow. | | Go: An exhibition at the Louvre will celebrate the 100th birthday of the French painter Pierre Soulages. The only other artists given similar shows during their lifetimes were Pablo Picasso and Marc Chagall. | | The tale of an eccentric family of deposed aristocrats who lived in a ruined palace was well known to foreign correspondents posted to India. But our reporter Ellen Barry kept returning to the story after her tenure as The Times’s Delhi bureau chief — and found an entirely new narrative. | | Her account reaches deep into the tumult of Britain’s partition of India and Pakistan, and explores how dislocation reshaped one family into an enduring legend. | | Ellen Barry, who was part of a team that won the Pulitzer Prize in 2011 for reporting in Russia. Andrew Testa for The New York Times | | We asked Ellen, who is now our New England bureau chief, why she couldn’t stop until she had found the real story. | | “It never entered my mind that I would be working on it for years,” she said. “But I was not able to answer the question of what the family’s history had been to my satisfaction.” | | Ellen said the story would have been impossible had she not had the backing of her editor, Jim Yardley. A former Times Delhi bureau chief himself, he had met the prince and encouraged her as she dug beyond the family’s fabled history. | | That’s it for this briefing.
