US halts Nvidia H20 chip exports over fears of China's misuse in AI
Taipei: The United States has enacted restrictions on the export of Nvidia's H20 chips to China, tightening its control over the trade of advanced AI technology with Beijing as part of Washington's strategy to exert pressure on China amid an ongoing tariff dispute, the Radio Free Asia (RFA) reported.
Nvidia, a prominent player in AI chip development worldwide, said on Tuesday that the US government informed them on April 9 that exporting its H20 chips to China would now necessitate government permission. The company also stated that this restriction would be in effect indefinitely.
Although the H20 chip has relatively limited computing capabilities, it possesses characteristics that make it suitable for constructing high-performance computing systems. The RFA report pointed out that the US government allegedly based its decision on fears that the H20 chips could be utilised in or modified for Chinese supercomputers.
The H20 was the most sophisticated artificial intelligence chip allowed for legal export to China, which was already under US national security-related restrictions on high-end semiconductor sales. While its performance does not match Nvidia's latest Blackwell chip, it is equipped with high-bandwidth memory akin to that used in Blackwell, offering a performance enhancement for certain applications, RFA reported.
The H20 chip attracted attention after it was used by DeepSeek, a Chinese AI startup that debuted a cost-effective and competitive AI model trained with the chip in January.
Earlier this year, the tech media outlet, The Information reported that leading Chinese tech firms, including Alibaba, Tencent, and ByteDance, collectively ordered over USD16 billion worth of H20 chips in the first quarter, marking a rise of more than 40% from the prior quarter, as noted by the RFA report.
The US first imposed export controls on AI chips targeting China in October 2022 and has since expanded the restrictions to encompass additional technologies and nations. The enforcement of the export limitation on H20 chips coincides with a rise in trade tensions between the US and China, according to the RFA.

US, China reach deal to ease export curbs
LONDON: US and Chinese officials said on Tuesday they had agreed on a framework to get their trade truce back on track and remove China's export restrictions on rare earths while offering little sign of a durable resolution to longstanding trade tensions. At the end of two days of intense negotiations in London, US Commerce Secretary Howard Lutnick told reporters the framework deal puts "meat on the bones" of an agreement reached last month in Geneva to ease bilateral retaliatory tariffs that had reached crushing triple-digit levels. But the Geneva deal had faltered over China's continued curbs on critical minerals exports, prompting the Trump administration to respond with export controls of its own preventing shipments of semiconductor design software, aircraft and other goods to China. Lutnick said the agreement reached in London would remove restrictions on Chinese exports of rare earth minerals and magnets and some of the recent US export restrictions "in a balanced way", but did not provide details after the talks concluded around midnight in London. "We have reached a framework to implement the Geneva consensus and the call between the two presidents," Lutnick said, adding that both sides will now return to present the framework to their respective presidents for approvals. And if that is approved, we will then implement the framework," he said. In a separate briefing, China's Vice Commerce Minister Li Chenggang also said a trade framework had been reached in principle that would be taken back to US and Chinese leaders. US President Donald Trump's shifting tariff policies have roiled global markets, sparked congestion and confusion in major ports, and cost companies tens of billions of dollars in lost sales and higher costs. The World Bank on Tuesday slashed its global growth forecast for 2025 by four-tenths of a percentage point to 2.3%, saying higher tariffs and heightened uncertainty posed a "significant headwind" for nearly all economies. — Reuters

Oman calls for international cooperation in science
The Sultanate of Oman is participating in the 2nd Belt and Road Conference on Science and Technology Exchange held in the People's Republic of China. The Omani delegation is headed by Dr Rahma bint Ibrahim al Mahrouqiyah, Minister of Higher Education, Research and Innovation. In her speech at the conference, Dr Rahma emphasised the importance of international cooperation in science and technology, praising the Belt and Road Initiative's role in strengthening scientific and research partnerships among participating nations. She also highlighted Oman Vision 2040 and its key pillars, which align with the objectives of the Science and Technology Exchange Initiative under the Belt and Road framework. She noted Oman's key achievements since its first participation in the initiative, including the signing of an MoU on science and technology cooperation. This has led to several collaborative programmes between Omani and Chinese universities, such as knowledge exchange in 'smart campuses,' enhanced scientific cooperation with Chinese private sector institutions — particularly global company Huawei — as well as student and researcher exchanges; and cultural cooperation through Chinese language education and Arabic teaching for non-native speakers. On the sidelines of the event, the Minister held talks with Lin Xin, Vice Minister of Science and Technology of the People's Republic of China, exploring ways to enhance scientific and technical exchange in priority research areas such as environmental sciences, food security, medicine, health sciences (including traditional medicine) and artificial intelligence. Discussions also covered expertise exchange in marine and ocean sciences, genetic resources and mutual invitations to scientific conferences, including the upcoming Arab-Chinese Conference scheduled in August 2025. Additionally, they reviewed cooperation in cultural exchange, teaching each country's language in higher education institutions and increasing mutual recognition of academic credentials. During her visit to Sichuan University in Chengdu, the Minister explored potential collaboration in scientific and research programmes, particularly in creative arts. She also discussed partnership opportunities between Omani private higher education institutions and the Chinese university, including joint exhibitions, young researcher training, bilateral research projects, cultural student events and cooperation in AI, IoT and modern technologies. — ONA

OQAE begins operational phase of clean energy project pipeline
MUSCAT: More than five years after its establishment as the clean energy investment arm of OQ Group, OQ Alternative Energy (OQAE) is set to formally commence the operational phase of its pivotal mandate. That phase will begin next year, when three mid-scale renewable energy projects—dubbed Riyah-1, Riyah-2 (both wind-based Independent Power Projects, or IPPs), and the North Oman Solar IPP—come online over the course of the year. Their launch marks OQAE's official entry into the operational phase of a portfolio that aims to deliver upwards of 7 GW of new renewable energy capacity through to 2030. The significance of this milestone in OQAE's evolution as the National Champion for Renewable Energy in Oman was emphasized in an exclusive interview highlighting how the Riyah-1, Riyah-2, and North Oman Solar projects align with OQAE's overarching mandate. That mandate rests on two main pillars: The first is the development of renewable energy and green hydrogen projects; the second is ensuring holistic development across the entire value chain and ecosystem, which includes project execution, competency development, supply chain investment, and strategic planning through to implementation. Integral to these objectives is the aim of attracting foreign direct investment (FDI) and advanced technology know-how into Oman. As announced last month, a joint venture comprising OQAE (51%) and TotalEnergies (49%) will develop the three projects at designated sites within the Block 6 concession of Petroleum Development Oman (PDO). The renewable electricity generated will be supplied to PDO under long-term Power Purchase Agreements (PPAs) at agreed tariffs. The OQAE–TotalEnergies JV will continue to own and operate the projects for the duration of the PPAs. According to the officials, partnering with a renowned integrated energy company like TotalEnergies aligns with OQ Group's strategy of leveraging the extensive experience and capabilities of global industry leaders. 'Unlike our well-established peers such as OQ Exploration & Production and OQ Refineries & Petroleum Industries, OQAE is just commencing its operational journey,' one executive noted. 'As a first step, our partnership spans not only Riyah-1, Riyah-2, and North Oman Solar, but also the 300 MW solar PV project that will contribute to the decarbonisation of the Marsa LNG bunkering project under construction at Sohar Port.' Meanwhile, Huadong Engineering Corporation—a subsidiary of Chinese contracting giant PowerChina—has already begun work on the three PDO-linked renewable energy projects. An initial batch of eight wind turbines is expected to arrive at the Port of Duqm for Riyah-1 in October. The supplier, Goldwind, a leading Chinese manufacturer, was awarded the contract to supply 36 turbines (18 for each site), each with a capacity of 117 MW, for the two wind farms. Solar PV panels for the North Oman Solar project will be supplied by Longi, a global leader in solar technology. More than 200,000 bifacial N-type panels, with a generation capacity of 128 MW DC, will be installed across a 3.5 km² site at Saih Nihayda in central Oman. The commercial operation dates are targeted for Q2 2026 for North Oman Solar and Q4 2026 for the wind farms. In addition to being the first clean energy projects to progress from concept to implementation, Riyah-1, Riyah-2, and North Oman Solar are also set to create a number of firsts for OQAE. They are the first to achieve Final Investment Decision (FID) and financial closure; the first wind projects to be financed locally by Omani banks—Bank Muscat and Ahli Bank; the first Wind IPPs in the world to exclusively power oil and gas projects; the first clean energy projects in which both the developers and end customers are from the oil and gas sector; and the first collaboration between oil and gas companies to advance the energy transition.
