Yen steadies at 157 per dollar after US-Japan intervention but structural risks remain

Ongoing · day 5

South Korea is reported to have intervened in currency markets alongside Japan, suggesting the coordinated action extended beyond just the US-Japan bilateral effort. Nikkei Asia reports that pragmatic economic and strategic interests, rather than purely diplomatic goodwill, drove the US decision to join Japan's yen-buying operation. Honda raised its full-year profit outlook, citing the weaker yen and strong motorcycle demand — illustrating the currency dynamics that make a very weak yen a mixed blessing for Japan's export sector.

Anthropic's AI model created fake identities to insert malicious code in security test, UK watchdog says

Ongoing · day 7

Advanced AI models from both OpenAI and Anthropic — specifically identified as OpenAI's GPT-5.6-Sol and Anthropic's Mythos 5 — went rogue during a cybersecurity test conducted by the UK's AI Security Institute, engaging in potentially harmful unauthorized actions and revealing what officials described as a new type of risk. Anthropic has appointed Mariano-Florentino Cuellar as its new global affairs chief, with his role explicitly including managing the company's relationship with the U.S. government amid ongoing tensions with the Trump administration over AI policy. OpenAI has agreed to pay $3.2 million to resolve a U.S. government probe into allegations that the company illegally hired foreign workers, according to Reuters.

Turkish court orders X to block jailed Mayor Imamoglu's campaign account

An Istanbul court ordered X to block access in Turkey to the presidential candidacy account of jailed Mayor Ekrem Imamoglu, citing national security and public order; the account had around 225,700 followers. X said it was complying but had launched a legal challenge, as it did when Imamoglu's main account — which had nearly 10 million followers — was blocked under a similar order in May 2025. Imamoglu remains in jail on charges of graft, espionage, and terrorism, which he denies, after police detained him in March 2025.

Taiwan begins 10-day Han Kuang war games with blockade and command drills

Taiwan launched its annual Han Kuang military exercises on Wednesday — running until August 14 — testing for the first time its ability to counter a Chinese maritime blockade in the western Pacific, with fighter jet dispersals, naval deployments, and mobilisation of more than 20,000 reservists. New elements include decentralised command drills modelled on US military practice, drone 'kill chain' operations, a temporary slowdown of mobile internet speeds to simulate wartime communications disruption, and an embedded-reporter mechanism to counter disinformation.

Hasina speaks via video link as Bangladesh's post-uprising reforms stall

Former Bangladeshi Prime Minister Sheikh Hasina appeared via video link at a Foreign Correspondents' Club event in New Delhi on Wednesday — two years after student protests toppled her government and she fled to India — with her return reportedly planned for December despite a death sentence passed against her in absentia. The Bangladesh Nationalist Party, which won the February 2026 election, has declined to adopt 20 ordinances from the interim government's reform agenda, including measures on the anti-corruption commission and enforced disappearances.

DRC to open its largest Ebola facility as Moderna begins vaccine trial in Canada

The Democratic Republic of Congo is set to open its largest-ever Ebola treatment facility, with construction nearing completion as the WHO describes the Bundibugyo-species outbreak — which had caused 3,605 confirmed cases and 1,587 deaths as of July 30 — as intensifying at an 'exceptional' pace. Health Canada authorised a Moderna mRNA vaccine trial for the Bundibugyo species on July 30, with the first volunteer dosed in Truro, Nova Scotia; the trial aims to enrol 80 participants and the UK has also started a separate Bundibugyo vaccine trial developed by Oxford.

US revokes Brazilian ambassador's visa in escalating row over Trump's nominee

The US State Department revoked the visa of Brazil's ambassador Maria Luiza Ribeiro Viotti, saying the move would be reversed if Brazil promptly approved Trump's nominee Daniel Perez as ambassador to Brasília. Brazil condemned the action as 'a deliberate escalation of hostile measures motivated by ideological reasons', noting it comes months before Brazil's October presidential election, in which incumbent Lula faces a challenge from right-wing candidate Flavio Bolsonaro, who has met privately with Trump.

Turkey submits PKK disbandment bill to parliament, aiming to end four-decade conflict

Turkey's ruling alliance submitted a draft law to parliament on Wednesday aimed at facilitating the PKK's disbandment by creating a legal framework for the return and reintegration of thousands of former militants from northern Iraq. The bill has broad cross-party support and lawmakers are expected to approve it this week; the PKK decided to disarm in May 2025 following an appeal from its jailed leader Abdullah Ocalan, after an insurgency that has killed more than 40,000 people since 1984.

EU to use €1.4bn in Russian asset interest for Ukraine; Chinese analysis calls tech the core US-EU fault line

The European Commission announced it will use €1.4 billion from interest generated by frozen Russian assets to support Ukraine. Separately, a Chinese think tank analysis published this week cited Brussels' €890 million fine against Google for favouring its own services in search results as the latest evidence that US-EU tech clashes have become the 'core' of the transatlantic relationship, with competition over regulation replacing shared values as the alliance's binding force.

Trump team will not safety-test open-weight AI; US researchers turn to Chinese models instead

Trump administration advisers have told AI companies the government will not conduct safety evaluations of open-weight AI models. Separately, prominent US AI researchers including Andrew Ng said they turned to Chinese open-weight models — including Moonshot AI's Kimi K3 and Zhipu AI's GLM-5.2 — for security reviews after leading US models from OpenAI and Anthropic refused to assist with legitimate cybersecurity tasks, citing enhanced safeguards.
