Mai Li Ni, a senior practitioner in cross-border e-commerce, talked about the recent tariff policy of the United States with obvious helplessness in his tone. He said that his most personal feeling is that this directly hit the survival space of e-commerce companies, freezing the entire industry and even the supply chain. The price comparison platform "Smart Exploration" said that they monitored 930 Amazon products that have increased in price since April 9. With the sharp increase in tariffs, the average price increase of these products reached 29%, covering multiple categories such as clothing, household goods, electronic products and toys. There are also several e-commerce platforms that announced that due to the increase in operating costs caused by "recent changes in global trade rules and tariffs", price adjustments will be implemented from April 25. Commodity prices have soared, and consumers and companies are under double pressure. In this regard, Mai Li Ni said that it is difficult for the US government to achieve its desired "manufacturing return" so simply by imposing tariffs.Conflict situation: 1. According to the Ukrainian Pravda: Russia lost 1,110 soldiers in the past 24 hours. 2. The Russian Chief of General Staff said that the Kursk region has been completely recovered, and the Ukrainian side said that this statement is untrue. 3. The Ukrainian military: Our troops continue to operate in the Belgorod Oblast of Russia. 4. According to the Ukrainian National News Agency: The Russian army launched 414 attacks in the Zaporizhia region at night. 5. A Russian drone attacked a nine-story residential building in the industrial area of Dnipropetrovsk, Ukraine, killing one person and injuring at least three people, including a child. 6. According to the Polish Armed Forces, a Russian military helicopter crossed Polish airspace and entered the Baltic territorial waters. The nature of the incident shows that Russia is testing the defense readiness of Polands air defense system. Peace talks: 1. Ukraine said it still takes time to finalize the text of the Ukrainian-US mineral agreement. 2. Zelensky announced a meeting with Trump and emphasized the realization of a comprehensive and unconditional ceasefire. 3. Russian Foreign Minister: Russia will not disclose the progress of the negotiations before the conclusion of the Russian-US negotiations on Ukraine. 4. Ukrainian President Zelensky is reportedly scheduled to meet with European Commission President von der Leyen on Saturday. 5. Ukrainian Presidential Office: Ukrainian President Zelensky met with French President Macron. 6. According to Interfax: Russian President Putin confirmed during a meeting with US Special Envoy Vitkov that Russia is ready to negotiate with Ukraine without preconditions. April 27, a person familiar with the matter said on Saturday that the European Central Bank has set up a special task force led by Vice President Guindos, which will seek ways to simplify European banking rules. The source said that the central bank governors of Germany, France, Italy and Finland also participated in the working group. However, the European Central Bank has no right to amend the rules-this is the prerogative of the European legislature in Brussels, so any recommendations of the special task force must be submitted to Brussels for review. It is reported that this action stems from a letter jointly sent by the governors of the central banks of Germany, France, Italy and Spain to the European Commission this year, calling for the simplification of "overly complex" European banking rules.

This year, Rolls-Royce (OTC:RYCEY) will begin testing a prototype of its UltraFan engine, the largest turbofan in the world, which is up to 25 percent more efficient than its first-generation Trent engines.


UltraFan chief engineer Andrew Geer told reporters at Rolls' headquarters in Derby, central England, before the beginning of the Farnborough International Airshow on Monday that the demonstrator's fan had a diameter of 370 cm, the maximum size achievable for widebody aircraft.


He remarked that the technology may be scaled down for other applications, such as the return of the British aerospace industry to the market for narrowbody aircraft.


UltraFan will be "frozen" until testing is complete, with no more investment until Boeing (NYSE:BA) or Airbus launch a new aircraft program, UltraFan CEO Warren East told the Financial Times last year.


Geer noted that UltraFan was not a single engine, but rather a platform for several technologies, and that many of its innovations could be implemented into Rolls' existing programs.


It contains carbon titanium fan blades instead of the hollow titanium blades of prior Trents and a 64 megawatt power gearbox, which is a record.


He claimed that the first test flight will also use 100 percent sustainable aviation fuel from Air BP (NYSE:BP), which is derived from vegetable oils rather than fossil fuels.


Chris Cholerton, president of civil aerospace, remarked, "The suite of technologies we are testing aboard the demonstrator will introduce new capabilities for future propulsion systems and provide opportunities to enhance our current fleet."


In addition to improving the performance of gas turbines, Rolls is also exploring hydrogen and hybrid electric technologies to power commuter and regional aircraft.


Beginning in the middle of the 2030s, the company intends to perform rig and engine tests to demonstrate that hydrogen can safely and effectively power small to medium-sized aircraft.


Liquid hydrogen will be utilized to power an AE2100 engine for the first time this year, according to the business, and a test of a Pearl 15 engine will follow at an unspecified date.
