WHAT WE ARE WATCHING

Trump's "Signing Summit" – On Sunday, Donald Trump announced that "substantial progress" in US-China trade negotiations had persuaded him to delay a tariff increase on $200 billion of Chinese goods that was set to take effect on March 1. He also suggested that Chinese President Xi Jinping's upcoming visit to Mar-a-Lago could become a "signing summit" for a broader trade deal. But there may be some tension between Trump's trade team – who want to put the screws to Beijing in order to seal a deal that really changes China's economic behavior – and Mr. Trump himself, who may favor a faster but fluffier "win" as he gears up for re-election. If Trump settles for a vaguer deal, he risks backlash from lawmakers and business people who want a harder line against Beijing.

State of Emergency in Sudan – Simmering protests against the 30-year rule of strongman Omar Bashir flared again over the weekend, even after he declared a state of emergency and reshuffled his cabinet. As we've written, discontent first erupted in December over economic issues, but the demonstrations quickly expanded into calls for Bashir's ouster. The removal of US sanctions in 2017 exposed the rot of Sudan's economy and stripped Mr. Bashir of a favorite explanation for his people's hardship. Gulf Arab countries have supported him, but the domestic situation in Sudan is getting more tenuous by the day.

WHAT WE ARE IGNORING

Vladimir Putin, music director – Amid an ongoing conflict between Russian authorities and the country's hip hop scene, President Putin has now ordered his government to submit proposals for supporting "contemporary popular music" and "genres that are in demand among youth audiences." This is part of his strategy to get the government to "direct" rather than stifle the burgeoning rap scene. This should go well – after all, you definitely want the guy who objects to music about "sex, drugs, and protest" to be on the 1s and 2s at the club. With his approval ratings at their lowest point in five years, Putin should probably think this through a little more carefully…

Something rooting in the state of Denmark – The world's various controversies over border security have made walls the emblem of our era, and now Denmark plans to build a 40-mile-long, five-foot-tall steel fence on its frontier with Germany. The unwanted migrants in this case? Potentially sickly wild boars. Now, it's natural for the Danish government to protect the 30,000 jobs at risk if Danish pigs fall ill, but will a wall do the trick? In some places the Germany-Denmark border is a river, and boars have been known to swim.
