In todayâ€s newsletter:
Bidenâ€s big policy shift on Ukraine
A deadly stabbing attack in China
Chinese investment boosts Hungaryâ€s recession-hit economy
Good morning. US President Joe Biden has authorised Ukraine to launch limited strikes into Russia using US-made long-range missiles, in a big policy shift before the end of his White House term in January, two people familiar with the decision said.
Bidenâ€s move comes in response to the deployment of thousands of North Korean troops to support Russia in its war against Ukraine, and after a barrage of new strikes on Ukrainian cities from Russia at the weekend.
Biden has long resisted allowing Kyiv to launch strikes within Russia using US-made long-range missiles known as Army Tactical Missile Systems, on the grounds that it could escalate tensions with Moscow.
But he is now dropping those objections with more than two months before he leaves office to make way for Donald Trump. Hereâ€s more on Bidenâ€s decision.
Russian strikes: Moscow yesterday launched dozens of missiles and drones in what Ukraineâ€s foreign minister said was one of the largest air attacks of the war.
More on North Korea: Pyongyang has supplied Moscowâ€s army with long-range rocket and artillery systems, a Ukrainian intelligence assessment has found.
And hereâ€s what else Iâ€m keeping tabs on today:
Economic data: Hong Kong reports October jobs data and Thailand releases third-quarter GDP.
UK-China ties: Keir Starmer will hold the first face-to-face talks by a British prime minister with Chinese President Xi Jinping since 2018, as he seeks “sensible and pragmatic engagement†with Beijing.
G20 summit: The gathering of the worldâ€s richest nations begins today in Rio de Janeiro, with Donald Trumpâ€s election as US president threatening to throw international initiatives on climate change and taxation into disarray.

2. Albemarle, the worldâ€s largest lithium producer, says it is not economically viable to build a supply chain in North America and Europe that could wrest control of critical minerals from China. The chief executive of the company, Kent Masters, told the FT that the US was “absolutely†at risk of losing the race to compete with China on the commodity, which is crucial for electric vehicle industry.
3. Donald Trumpâ€s advisers have sought assurances from the top candidates to be Treasury secretary that they are committed to his sweeping tariffs plans, people familiar with the discussions said. Scott Bessent, a hedge fund manager, and Howard Lutnick, the chief executive of financial firm Cantor Fitzgerald, are locked in a tight battle for the top economic cabinet post in the next administration.
4. A Social Democrat politician has joined the calls for the popular defence minister Boris Pistorius to run as the partyâ€s candidate for chancellor in Februaryâ€s snap elections instead of Olaf Scholz. Joe Weingarten became the first sitting SPD MP to call for Pistorius to enter the race, in a sign of growing concern in the party over Scholzâ€s low approval ratings.
5. Northvoltâ€s fate is hanging in the balance as the troubled Swedish battery maker considers filing for Chapter 11 protection from creditors or even bankruptcy. People involved in the negotiations about the future of the one-time big hope for Europeâ€s automotive industry said that its future was likely to be decided in the coming days after talks about a rescue package recently collapsed.
News in-depth
Hungary under President Viktor Orbán has captured more than a quarter of all Chinese investment coming into Europe over the past two years. The outsized share has boosted an otherwise struggling Hungarian economy hit by the EU withholding about €20bn of funding over rule of law concerns. Orbánâ€s challenge now is pulling off the diplomatic gymnastics required to simultaneously remain an ally to Xi Jinping and Donald Trumpâ€s incoming administration of China hawks, while managing the threat of a chronic decline in EU funds.
