A scaled-down rocket engine smaller than a ₹1 coin
A 3D-printed, scaled-down model of a liquid propulsion rocket engine placed on a ₹1 coin is among the draws at a small exhibition that has opened alongside the two-day national conference on Emerging Vistas in Chemical Engineering (EVINCE 2025) here in the city.
The 3D-printed model is on display at the stall of Shree Rapid Technologies (SRT), Mumbai. The model has been created using a 3D printer of the U.S.-based Boston Micro Fabrication (BMF), of which SRT is the general partner in India. BMF printers can print feature sizes as small two microns, an SRT official said.
While the rocket engine model simply illustrates the capability of such 3D printers, small 3D printed parts actually find application in microelectromechanical and microfluidic systems. The two-day national conference, which is on at hotel Hyatt Regency, is being organised by the Indian Institute of Chemical Engineers (IIChE), Thiruvananthapuram chapter, and will conclude on Saturday.

India will protect farmers' interest in U.S. trade talks: Shivraj Singh Chouhan
India will prioritise protecting its farmers' interests while assessing potential gains and losses in the ongoing trade negotiations with the U.S. over agricultural market access, Union Agriculture Minister Shivraj Singh Chouhan said. "Our priority is to protect the interest of our farmers. India will not work closing its eyes. We will assess our gains and losses. Keeping that in mind, an agreement will be finalised," Mr. Chouhan told the PTI in an interview. He was responding to a query on how India would safeguard farmers amid pressure from the U.S. for greater market access for American agricultural and horticultural products. The negotiators are expected to agree on the framework for the broad contours of the first phase of the bilateral deal, expected to be signed by fall (September-October) 2025. "The discussions are ongoing between India and the U.S. One thing is clear, we will protect the interest of our farmers. When we talk about two nations, we need to see the overall trade," the Minister added. According to a NITI Aayog report on 'Promoting India-U.S. Agricultural Trade under the new U.S. Trade Regime', the value for U.S. agriculture and allied product exports to India was about $2.22 billion in the triennium ending 2024. In the same period, India exported $5.75 billion worth of agricultural products to the U.S. India's main agricultural exports to the U.S. include frozen shrimp, basmati rice, spices, processed cereals, and other value-added products. The U.S. wants to export more agricultural products, including corn, soybeans, and animal feed, but faces high Indian tariffs, especially in agriculture, where average tariffs can reach up to 39% to 50%. Mr. Chouhan's comments come as India and the U.S. continue negotiations on expanding agricultural trade, with Washington seeking reduced tariffs and improved market access for its farm products in the Indian market. India is cautious about fully opening its agriculture and dairy markets due to concerns over the potential backlash from rural communities, and the need to protect domestic producers from global price volatility.

UK finance minister Reeves to meet China's vice premier on London trip
LONDON, - British finance minister Rachel Reeves will hold a meeting with Chinese vice premier He Lifeng during his visit to Britain this week for trade talks with the United States, a British government source said on Sunday. China's foreign ministry said He would be in Britain between June 8 and June 13 when there will be talks in London with three of U.S. President Donald Trump's top aides to try to resolve a trade dispute between the world's two largest economies that has kept global markets on edge. The British government source said Reeves would host He for a bilateral meeting during the trip, although there were no details on when the talks would be held. The British finance minister met He during a visit to China in January, part of British attempts to improve ties with Beijing, one of the main policy goals of Prime Minister Keir Starmer's government. However, many British lawmakers remain sceptical of China amid regular accusations of espionage by spies working for Beijing, and plans for a new large Chinese embassy in London remains a divisive subject, with the opposition Conservative Party saying it must be blocked. The Chinese government wants to build the embassy at Royal Mint Court, a historic site near the Tower of London, which would be its largest in Europe but its requests for planning permission have been rejected by the local council, and the government will make a final decision. The Sunday Times reported that a senior U.S. official had said Washington was "deeply concerned" about the plans, due to its proximity to London's financial hubs and three significant data centres, and approval could impact UK-U.S. trade talks. "These issues will be taken care of assiduously in the planning process," British technology minister Peter Kyle told Sky News on Sunday.

India, U.S. trade talks extended as deadline looms for interim deal, sources say
Trade talks between Indian and U.S. officials have been extended into next week as both sides seek consensus on tariff cuts in the farming and auto sectors, aiming to finalise an interim deal before a July 9 deadline, government sources said. A U.S. delegation led by senior officials from the Office of the United States Trade Representative (USTR) held two days of discussions in the national capital with trade officials headed by chief negotiator Rajesh Agrawal, the sources said. Also Read | India-U.S. trade deal in 'not too distant future': U.S. Commerce Secretary Lutnick "The two countries are actively engaged in focused discussions to facilitate greater market access, reduce tariff and non-tariff barriers, enhance supply chain resilience and integration," one Indian government official with direct knowledge of the talks, said. Negotiators, who had initially aimed to wrap up talks by Friday, will now continue discussions on Monday and Tuesday to resolve outstanding differences, a second official said. U.S. President Donald Trump and Prime Minister Narendra Modi had agreed in February to conclude a bilateral trade pact by fall 2025 and more than double trade to $500 billion by 2030. The current talks are part of efforts to hammer out a limited trade agreement that could lead the Trump administration to revoke 26% reciprocal tariffs on Indian goods - tariffs that have been paused along with those on several other U.S. trading partners for 90 days, the second official said. "Many Indian exporters have held back shipments to the U.S. in the last two weeks, fearing cargos may not reach before the July 9 deadline,' the official added. India's exports to the U.S. jumped nearly 28% year-on-year to $37.7 billion in the January–April period, driven by front-loading of shipments ahead of tariff hikes in April, while imports rose to $14.4 billion, widening the trade surplus in India's favour, according to US government data. Centre approved a licence for Elon Musk's Starlink to launch commercial operations, ignoring his public spat with Mr. Trump, Reuters reported on Friday. India is opposing U.S. demands to open up its agricultural and dairy markets, another Indian official said, citing the impact on millions of poor farmers who cannot compete with heavily subsidised American products. Indian officials have also made it clear New Delhi could pursue its complaint at the World Trade Organisation against the U.S. tariff hikes on steel and aluminium, while aiming to work out a bilateral agreement, the source added.
