The IAEA said a drone struck the cooling tower of an operating reactor unit at the Kursk nuclear power plant on 17 September, causing minor damage but no disruption to output or radiation levels.

Trump signed the Lindsey O. Graham Sanctioning Russia and Iran Act, authorising sweeping new sanctions on Russian officials, banks and energy revenue and on Iran's weapons and energy sectors. The State Department separately approved a possible $2.68 billion sale of air-defence equipment to Ukraine. RFE/RL / CP24
Trump announced an agreement with Denmark on 18 September giving the US what he called 'permanent control' over Greenland's security, though the island remains formally part of Denmark, short of the outright control he had earlier demanded. The pact is expected to be signed at the UN General Assembly next week. NBC News / Washington Post
Trump said he was banning CNN, MS NOW and Politico from the White House 'effective immediately' over what he called biased coverage; by Saturday the outlets said their reporters had been denied access and had press credentials confiscated. All three said they would pursue legal action. CNN / Washington Post
A Chinese coast guard ship and a Philippine fisheries vessel delivering subsidised fuel to fishermen collided twice on 18 September in the South China Sea, bending and breaking railings on the Philippine ship.

The onshore yuan touched 6.6853 per dollar on 18 September, its strongest since June 2022, after the PBOC strengthened its daily fixing for an eighth straight session. Traders linked the move to strong exports and to Beijing signalling comfort with a firmer currency ahead of Xi Jinping's 24 September meeting with Trump. Bloomberg / Caixin
Xi Jinping is due to arrive in Washington on 23 September for his first visit to the US capital in over a decade, meeting Trump the next day for talks expected to cover trade, critical minerals, AI governance and Taiwan.

The city's first post-handover chief executive, Tung Chee-hwa, who died on 8 September aged 89, was honoured at a state funeral at Hong Kong Funeral Home on 20 September, only the territory's third since 1997.

Authorities staged a joint fire and rescue exercise at the new joint-inspection building of the rebuilt Huanggang checkpoint on the evening of 18 September, part of testing before a formal opening date is set. The co-located facility is designed to let border officers from both sides clear passengers in a single stop. RTHK / TVB News

US stocks closed a turbulent week mixed on Friday 18 September. The S&P 500 edged up 0.16% to 7,650, the Dow slipped 0.18% to 51,683, and the Nasdaq added 0.39% to 26,522; for the week the S&P was down about 0.1%, the Dow lost 1.7% and the Nasdaq gained 0.7%. The week was dominated by the Federal Reserve's quarter-point rate hike on 16 September, lifting the target range to 3.75%-4.00% in its first increase since 2023, with policymakers signalling another hike is possible before the next meeting on 27-28 October.
The US 10-year Treasury yield climbed to 5.01% on 16 September, its highest point of this run, before easing to 4.94% by 17 September, the latest reading in the dashboard, which lags the equity data by a day or two. Oil was the other big macro story: WTI crude, which spiked as Houthi forces advanced along Yemen's Red Sea coast and threatened Saudi oil infrastructure and the Bab el-Mandeb strait, stood at $107.02 on 15 September, up from about $94 on 8 September and the most recent print available in the dashboard.
Among individual names tracked in the dashboard, chipmakers had a rough patch around mid-week before rebounding into the weekend amid broader unease over the pace of AI development. Nvidia closed 18 September at $222.27, up from a mid-week low of $210.96 on the 14th; Broadcom recovered to $357.61 from a low of $339.27; and Micron jumped to $1,015.80 ahead of its next earnings report, due 30 September. TSMC edged up to $434.67.
Microsoft was little changed at $493.78, while Palantir extended its rally to $177.64, up roughly 6% on the week and more than 40% since late July. Block continued to slide, closing at $76.28, its lowest level in the dashboard's history back to late July, while SoFi edged up to $16.96 on Friday after touching $16.73 the day before, still ending the week lower.
In crypto, Bitcoin rose to $81,233.91 and Ethereum to $2,631.70 by 19 September, the latest data available, both up modestly after the Fed's decision removed some uncertainty. A bill meant to set clearer US market-structure rules for digital assets, the CLARITY Act, remains stalled after a Senate cloture vote failed 49-50 on 15 September.
In Hong Kong, the Hang Seng Index closed up 0.6% at 24,750.78 on 18 September, helped by the strengthening yuan, which touched its firmest level since 2022 against the dollar — a move traders read as a sign Beijing is comfortable with currency strength ahead of the Trump-Xi summit.

Anthropic is reportedly delaying its planned listing from October to November so it can present stronger third-quarter results, with investors anticipating a valuation near $2 trillion and a raise of up to $100 billion — potentially the largest IPO on record. Bloomberg / crypto.news
A lawsuit filed around 19 September alleges Anthropic, OpenAI, xAI and Google made an illegal pact to throttle AI development, after the four companies' leaders publicly backed Anthropic chief executive Dario Amodei's earlier call for a coordinated slowdown, or 'pacing the frontier,' to give safety research time to catch up. CNN Business / The Hill
Anthropic named Accenture's Faculty unit as its first embedded evaluator on 18 September, with each company pledging at least $1 billion over five years for red-teaming, alignment testing and safeguard reviews; Faculty staff will get employee-level access to Anthropic's training and deployment decisions. AI Weekly
Researchers disclosed a zero-click remote-code-execution bug on 17 September that lets a malicious plugin bypass SHA-pinning checks in Claude Code, OpenAI Codex, GitHub Copilot and Google's Gemini CLI. Anthropic and OpenAI have shipped patches; Microsoft and Google have not fully fixed the flaw, with Google instead steering users to a successor tool. The Hacker News / Help Net Security
In a Truth Social post on 19 September, Trump said he would create an 'AI Force' modelled on the Space Force and name a new AI czar to oversee the industry, arguing AI could generate a quarter of US GDP and that the country must stay ahead of China. Al Jazeera / NBC News
