The briefing for Monday, September 28.

The United States and China released reciprocal lists Monday of products worth about $30 billion each that will see tariff cuts, formalizing a deal that followed Chinese President Xi Jinping's state visit to Washington last week. China's list covers 1,619 categories of U.S. goods, including agricultural commodities and coal, while the U.S. list covers 77 categories of Chinese exports like toys and Christmas ornaments. Tariff rates on over 90% of these products will effectively be reduced to "most-favored-nation" levels, according to China's commerce ministry.

Notably absent from the deal were strategic sectors like semiconductors, electric vehicles, and rare earth minerals, and there was no mention of Taiwan in the White House's summary of the talks. According to Chinese state media, Xi pressed Trump to formally oppose Taiwan independence during their private discussions. Trump told reporters afterward that the topic came up only briefly, saying "it's just moving along" and that Xi "understands very much how I feel."

Adding a striking wrinkle, U.S. Ambassador to China David Perdue told Fox News that Trump had asked Xi directly whether he'd like to buy American weapons, seemingly as a way to downplay the significance of a pending $14 billion arms package for Taiwan that has been on hold for months. The State Department clarified that U.S. law prohibits arms sales to China and there are no plans to pursue one. China's foreign ministry did not confirm or deny Perdue's account when asked Monday.

The two countries also extended their broader trade truce to January 10, a shorter reprieve than Beijing had reportedly hoped for. Analysts say the $30 billion tariff deal, while economically modest compared to overall trade volumes, could meaningfully boost U.S. exports to China and ease some inflationary pressure on American consumers. The unresolved questions around Taiwan arms sales and the ambiguous U.S. posture on the island, however, leave open bigger strategic questions about the relationship going forward.

The Trump administration on Monday released new fuel economy standards that relax pollution control requirements for gasoline-powered vehicles, projected to lower the industry fleetwide average to roughly 34.5 miles per gallon by the 2031 model year, down from a Biden-era projection of 50.4 mpg. President Trump said on Truth Social that the change would "take the waste out of building cars in America" and save families money on new vehicles while boosting domestic auto production.

The move continues a broader pattern of the administration unwinding EV-related policies, including relaxed tailpipe emissions rules, repealed fines for automakers missing mileage standards, and the termination of up to $7,500 in consumer EV tax credits. The administration and automakers argue the new rules will make gasoline vehicles more accessible and affordable, though the change arrives as the average new car price topped $50,000 in August for the first time since December, according to Kelley Blue Book.

Environmental groups sharply criticized the timing, given that gas prices have surged amid the ongoing U.S.-Iran conflict, hitting a national average of $4.47 a gallon Sunday, up from $4.09 a month earlier, according to AAA. The Center for Biological Diversity's Dan Becker called the rollback ill-timed for consumers "getting hit with sky-high prices at the pump," while the Sierra Club's Katherine García warned that less efficient vehicles mean more money spent on gas.

The 2024 standards being replaced were projected to save 14 billion gallons of gasoline by 2050; NHTSA estimates that without them, cars could produce over 22,000 more tons of pollutants by 2035. The rollback represents one of the most significant reversals yet of climate-era vehicle regulation, with implications for both household budgets and long-term emissions trends.

Fighting has intensified around Yemen's third-largest city, Taiz, as Houthi rebels battle Saudi-backed government forces for control of high ground overlooking the city's southern routes. The BBC reported from the front lines, where residents described mortar strikes landing near their homes and soldiers described bodies of fallen comrades that remain unretrievable in contested territory between the two sides.

The clashes have escalated since Houthi forces seized the strategic Red Sea port of Mokha on September 10, breaking a ceasefire that had largely held for four years. That seizure gave the Houthis control over territory overlooking the Bab al-Mandab Strait, a vital shipping corridor linking Europe and Asia, and contributed to rising oil prices amid fears of further supply disruption.

Government forces currently hold central Taiz, with Houthi positions to the north and east; both sides are said to be preparing for a larger offensive in the days ahead. The fractured nature of anti-Houthi forces—marked by roughly 30 checkpoints controlled by different commanders along the route from Aden—illustrates the complexity of the government coalition's response.

The renewed fighting adds another pressure point to global oil markets already strained by the Iran conflict, and raises the stakes for a shipping lane critical to international trade. A Houthi victory in the surrounding highlands could make it significantly harder for government forces to retake the port of Mokha, entrenching the group's control over the strait.

Confirmed Ebola cases in Congo have surged past 8,000, with the health ministry reporting 8,067 cases and 3,901 deaths as of September 26 across 63 health zones in seven provinces. The outbreak, caused by the rare Bundibugyo virus strain for which there is no known treatment or vaccine, has a fatality rate exceeding 48%, according to the latest figures.

The World Health Organization said Congo is running out of health workers to contain the disease, with staff reporting delayed or missing payments that have triggered strikes despite the outbreak's severity. At least 50 health workers have died since the outbreak began, according to the Africa Centers for Disease Control and Prevention. The WHO noted that a persistently high rate of deaths occurring in communities, rather than in medical care, points to ongoing challenges in early detection and treatment access.

While some regions, including Ituri and Haut-Uele provinces, have seen case numbers decline, the disease continues to spread into new areas. Data from the Africa CDC shows the current outbreak has outpaced the 2014-2016 West Africa epidemic in terms of speed of spread at comparable points in time, and WHO officials say it is on track to surpass that outbreak's death toll of 11,000.

Insecurity, population displacement, and the health worker strikes have all hampered containment efforts. With no approved treatment or vaccine for this viral strain, health officials face mounting pressure to stabilize the healthcare workforce before the outbreak spreads further.

Serbian President Aleksandar Vucic resigned Sunday, clearing the way for an early parliamentary election on October 25 in which he plans to run for prime minister instead. Barred by the constitution from seeking a third presidential term, Vucic said he was stepping down to lead his right-wing Serbian Progressive Party into the vote, a move widely seen as a calculated maneuver to retain power despite nearly two years of anti-government protests.

The unrest was triggered by the November 2024 collapse of a train station canopy in Novi Sad that killed 16 people, an incident that galvanized a broad, youth-led movement demanding accountability and anti-corruption reforms. That movement, now organized as an electoral list called Students Win, includes professors, athletes, and other citizens with little political experience, and is polling closely with Vucic's party, according to analysts who describe the race as a referendum-like contest.

Ana Brnabic, a close Vucic ally and outgoing parliamentary speaker, will serve as acting president until a new presidential election is held, which Vucic said must occur within 90 days of his resignation. Before leaving office, Vucic pardoned 49 people, including 23 students and party loyalists connected to offenses during the unrest. Vucic and his party have faced longstanding allegations of corruption and control over state institutions, which they deny.

The dual elections—parliamentary in October, presidential later this year—will test whether Vucic's 14-year grip on Serbian politics can survive sustained public discontent. His decision to shift to the more politically dominant but formally less powerful role of prime minister underscores his intent to remain the country's central political figure regardless of the outcome.
