Fukushima debris removal delayed until 2037 or later
Fukushima Daiichi nuclear power plant said the start of full-scale removal of melted fuel debris would be delayed for several years until 2037 or later, the latest setback underscoring the challenges ahead.

The Tokyo Electric Power Company Holdings (Tepco) said on Tuesday it would need 12 to 15 years of preparation before starting full-scale removal of melted fuel debris at the No 3 reactor. That preparation includes reducing radiation levels and building necessary facilities in and around the reactor.
Overall, at least 880 tons of melted nuclear fuel have mixed with broken parts of internal structures and other debris inside the three reactors that suffered meltdowns at the plant following the 2011 earthquake and tsunami.

The delay again sets back the 2051 target set by
Japan 's government and Tepco for decommissioning the plant.
A test retrieval of a tiny sample of melted fuel debris in November was already three years behind, and some experts estimate that the decommissioning work could take more than a century.
Tepco said it plans to stick to the current completion target of 2051.

'Realistically, we are aware of the difficulty [to achieve the target] but we will not drop the goal just yet, as we still don't have a clear work schedule after the full-scale removal begins,' said Akira Ono, chief decommissioning officer at Tepco.

Taiwan vows to seek lower tariff after Trump's ‘temporary' 20% levy
Taiwan vowed on Friday to seek a lower tariff after Donald Trump imposed a 'temporary' 20 percent levy on its shipments to the United States as part of his trade war. The US president's announcement was part of a sweep of measures — reaching 41 percent — against dozens of global partners as they scrambled for deals with Washington to avert the painful tolls. The figure is down from the 32 percent toll imposed in his April 2 'Liberation Day', since when Taipei and Washington have held four rounds of face-to-face talks and multiple video conferences to resolve the issue. On Friday Taiwan President Lai Ching-te said on Facebook they were still working to strike an agreement 'The US has announced a temporary 20 percent tariff for Taiwan, with the possibility of further reductions should an agreement be reached,' he wrote. 'The government will continue to strive for a reasonable tariff rate and complete the final stages of the tariff negotiations.' While Trump had set Friday as the deadline for agreements to be made, he delayed it until the end of next week. No timeline was given for Taiwan, which could mean the island was caught in the middle of US-China trade negotiations, said Alicia Garcia-Herrero, chief economist for Asia Pacific at Natixis. Washington and Beijing held two days of talks this week aimed at reaching a deal to extend a truce in their trade war and prevent the reimposition of sky-high tariffs on August 12. 'The conditions on Taiwan might be relevant for China, imagine export controls,' Garcia-Herrero told AFP. After US tech giant Nvidia announced it will resume sales of its H20 AI chips to China, Garcia-Herrero said 'there could be other stuff that China needs from Taiwan that the US can offer'. 'This is the ceiling' Taiwan is a global powerhouse in chip manufacturing, with more than half the world's semiconductors and nearly all of the high-end ones made there. The owner of a Taiwanese machinery exporter to the United States said he was worried that lower tariff rates on Japan and South Korea — 15 percent — would advantage his competitors there. He told AFP the recent appreciation in the Taiwan dollar against the greenback had also 'put a lot of pressure on us, creating a double whammy'. The uncertainty over tariffs was hurting US sales, said textile producer Eddie Wang, with clients 'feeling overwhelmed' and reluctant to place orders. Soaring demand for AI-related technology has fuelled Taiwan's trade surplus with the United States — and put it in Trump's crosshairs. Around 60 percent of Taiwan's exports to the United States are information and communications technology, which includes chips. In a bid to avoid the tariffs, Taipei has pledged to increase investment in the United States, buy more of its energy and increase its own defence spending. Economist Sun Ming-te said the 20 percent levy was 'probably the best outcome Taiwan can achieve with the US under the current conditions.' 'This is the ceiling, and it can go lower in the future,' Sun, from the Taiwan Institute of Economic Research, told AFP.

Trump trade deal marks Europe's capitulation Diego Faßnacht argues that the new EU-US trade agreement, hailed by Brussels as a path to stability, actually codifies Europe's economic subordination to Washington, outsourcing its defense, energy, and industrial policy at a time of escalating global tensions. Putin under pressure as Trump eyes secondary sanctions James Davis reports that the Ukraine crisis is entering a more volatile phase with Trump's public disavowal of Putin ending a nascent US-Russia rapprochement. Kremlin insiders reportedly fear Trump will impose sweeping secondary sanctions on buyers of Russian energy. In Japan, unwritten deals and unsettled leadership Scott Foster assesses that Japanese Prime Minister Shigeru Ishiba is likely to survive mounting internal pressure to resign. Meanwhile, trade tensions with the US are drawing concern, as Japan has avoided formalizing a recent deal with Washington.

HK stocks retreat on factory data
HK stocks retreat on factory data The Hang Seng Index ended trading down 403 points, or 1.6 percent, at 24,773 on Thursday. File photo: AFP Mainland stocks on Thursday posted their steepest one-day decline since April. Analysts said sluggish factory data weighed on sentiment. In Hong Kong, the benchmark Hang Seng Index ended trading on Thursday down 403 points, or 1.6 percent, at 24,773. The Chinese H-share index listed in Hong Kong, the Hang Seng China Enterprises Index fell 1.7 percent, and mainland developers listed in the city fell 4.3 percent. Up north, the benchmark Shanghai Composite Index closed down 1.18 percent at 3,573 while the Shenzhen Component Index ended 1.73 percent lower at 11,009. The combined turnover of these two indices stood at about 1.94 trillion yuan, up from 1.84 trillion yuan on Wednesday. Stocks related to glass and bio-pharmaceutical sectors led gains while stocks in the nonferrous metal and furniture industries suffered major losses. The ChiNext Index, tracking China's Nasdaq-style board of growth enterprises, lost 1.66 percent to close at 2,328. The pullback broke a rally that had briefly carried the Shanghai index into bull territory. Still, the benchmark advanced 3.7 percent in July, its best performance since September and a third straight month of gains. Fresh data showed China's manufacturing activity shrank for a fourth straight month in July as demand at home and abroad weakened, further dampening the growth outlook. (Reuters/Xinhua)
