On July 8, Ukrainian President Zelensky, who was visiting Poland, and Polish Prime Minister Tusk signed a bilateral security agreement in Warsaw, the capital of Poland. The agreement clearly states that Poland will provide support to Ukraine in air defense, energy security and reconstruction. After signing the agreement, Tusk said that the agreement includes actual bilateral commitments, not "empty promises." Previously, the United States, Britain, France, Germany and other countries as well as the European Union signed similar agreements with Ukraine.

WASHINGTON, June 24 (Reuters) - Problems with Boeing's Starliner capsule, still docked at the International Space Station (ISS), have upended the original plans for its return of its two astronauts to Earth, as last-minute fixes and tests draw out a mission crucial to the future of Boeing's (BA.N), opens new tab space division. NASA has rescheduled the planned return three times, and now has no date set for it. Since its June 5 liftoff, the capsule has had five helium leaks, five maneuvering thrusters go dead and a propellant valve fail to close completely, prompting the crew in space and mission managers in Houston to spend more time than expected pursuing fixes mid-mission. Here is an explanation of potential paths forward for Starliner and its veteran NASA astronauts, Barry "Butch" Wilmore and Sunita "Suni" Williams. THE CURRENT SITUATION Starliner can stay docked at the ISS for up to 45 days, according to comments by NASA's commercial crew manager Steve Stich to reporters. But if absolutely necessary, such as if more problems arise that mission officials cannot fix in time, it could stay docked for up to 72 days, relying on various backup systems, according to a person familiar with flight planning. Internally at NASA, Starliner's latest targeted return date is July 6, according to this source, who spoke on condition of anonymity. Such a return date would mean that the mission, originally planned for eight days, instead would last a month. Starliner's expendable propulsion system is part of the craft's "service module." The current problems center on this system, which is needed to back the capsule away from the ISS and position it to dive through Earth's atmosphere. Many of Starliner's thrusters have overheated when fired, and the leaks of helium - used to pressurize the thrusters - appear to be connected to how frequently they are used, according to Stich.

Editor's Note: This year marks the 10th anniversary of the Belt and Road Initiative (BRI) proposed by Chinese President Xi Jinping. Through the lens of foreign pundits, we take a look at 10 years of the BRI - how it achieves win-win cooperation between China and participating countries of the BRI and how it has given the people of these countries a sense of fulfillment. In an interview with Global Times (GT) reporter Li Aixin, Erik Solheim (Solheim), former under-secretary-general of the United Nations and former executive director of the UN Environment Programme, recalled how the BRI helped shorten a previously long journey in Sri Lanka to a half-hour trip. "We will all be losers in a de-globalized, de-coupled world. The BRI can play a key role in bringing the world together," Solheim said. This is the 18th piece of the series. GT: How do you evaluate the role of the BRI in promoting development in participating countries over the past 10 years? Solheim: The BRI has been a major driver of development since it was announced by President Xi Jinping in Kazakhstan 10 years ago. The China-Laos Railway has connected landlocked Laos to the Chinese and European rail network, making it possible for Laos to sell more goods and welcome more tourists. Rail corridors in Kenya and from Djibouti to Addis Ababa connect the interior of Africa to the coast, bringing opportunities for much faster development in East Africa. The Bandung-Jakarta railway in Indonesia, Hanoi metro, roads and ports in Sri Lanka - there are great examples of good south-south and BRI projects in almost every corner of the world. GT: In your experience of traveling around the world, has any BRI-related story left a deep impression on you? Solheim: Yes, many! I'll just mention two. When I was chief negotiator in the Sri Lanka peace process 15 years ago, it took a long time to travel from the airport to Colombo, the capital of Sri Lanka. When I came back last year, it took half an hour on wonderful Chinese-built highways. Traveling through Mombasa, a coastal city in Kenya, you see a lot of poverty and run down houses. Then all of a sudden, a green, clean, well-run oasis opens up. It's the end station of the Nairobi-Mombasa railway which links the capital Nairobi to the coast. The rail station stands out and is showing the future for Kenya. GT: The EU proposed the Global Gateway, and the US proposed the Build Back Better World. What do you think are the similarities and differences between these projects and the BRI? Solheim: I really wish success for the Western initiatives. What developing nations ask for is a choice of good cooperation with both China and the West. Unfortunately, up to now, a number of the Western-led initiatives have been more like media events. They lack structure, secretariat, finances and clear direction. Nearly all nations in the world want to see close people-to-people relations, investment and political cooperation with both China and the West. No one wants to choose. GT: Some people from the West are talking about "de-coupling" and "de-risking." Both seem to be another way of saying "de-globalization." Do you think "de-coupling" and "de-risking" will affect the BRI? And what role will the BRI play in maintaining globalization? Solheim: Decoupling is probably the most unwise idea in the world today. It's outright dangerous. Facing climate change, environmental degradation, economic troubles, war in Ukraine and other places, and the threat of pandemics, we need more, not less, cooperation. We will all be losers in a de-globalized, de-coupled world. The BRI can play a key role in bringing the world together. Almost all developing countries have made BRI agreements with China. As an example, when President Xi met all the leaders of Central Asia recently in Xi'an, Northwest China's Shaanxi Province, they made a very ambitious declaration on future green cooperation between China and Central Asia. GT: You have previously said that the BRI is a fantastic vehicle to promote green global development, which can boost the economy and ecology at the same time. Could you elaborate on how you think the BRI has achieved development of the economy and ecology? Solheim: In the beginning there were too many fossil fuel projects among BRI programs. In the BRI International Green Development Coalition, we argued this should stop. When President Xi pledged to stop building new coal-fired power projects overseas, it was one of the most important environmental decisions ever. Also, it happened at a time when important BRI nations like Bangladesh, Kenya and Pakistan decided they could grow their economies and go green without coal. The BRI will in the next decade become the world's most important vehicle for green energy and green transport. We will see massive investments in solar and wind power, hydrogen, electric batteries and more. GT: How do you view China's goal of achieving harmony between humanity and nature in modernization? In what way is China's story in pursuing harmony between humanity and nature relevant to other countries? Solheim: China now covers between 60 percent and 80 percent of all major green technologies in the world - solar, wind, hydro, batteries, electric cars and high-speed rail. Companies like Longi, BYD and CATL are the world leaders in their sectors. More remarkably and maybe less noticed abroad, China is also a global leader in protecting nature. It's embarking upon one of the most massive national park programs, with a focus on Qinghai Province and Xizang Autonomous Region. China is by far the biggest tree planter in the world and the global leader in desert control in Kubuqi, Inner Mongolia and other places. China has been hugely successful in the recovery of endangered species like the Giant Panda, Tibetan Antelope and Snow Leopard. A new center for mangrove restoration is being set up in Shenzhen and the fishing ban in the Yangtze will restore that magnificent ecosystem. The Belt and Road is a great opportunity for the world to learn from good Chinese green practices.

In fact, ChatGPT can bring more opportunities to many industries, such as customer service, marketing, speech recognition, and more. ChatGPT can help businesses engage with customers more effectively, improve the customer experience, and give businesses more time and resources to focus on other tasks. Come to see While ChatGPT can replace humans in certain situations, it is not a complete replacement for humans. In many cases, human-to-human communication is still the most effective way. Therefore, the emergence of ChatGPT will not lead to the unemployment of all people, but will cause structural changes in the labor force and the redistribution of occupations.

The world's first portable electrocardiograph was an 85-pound backpack, and now a 10-gram patch attached to your chest can transmit electrocardiograms uninterrupted for two weeks. The Apple Watch, which is worn by an estimated 100 million people, can send a text message to alert people when their heartbeat is irregular. Wearable sensors on the arms, wrists and fingers can now report arrhythmias, blood sugar levels, blood oxygen and other health indicators. Medical journals have also proposed a more ambitious vision - wearable devices can monitor patients with chronic diseases, eliminating the need for frequent hospital visits. They can spot potential health problems before a stroke or diabetes develops. The forces of health technology and wearables are converging. Tech giants like Apple (AAPL) and Alphabet's (GOOGL) Google are adding health features to their products. Medical technologists like electrocardiogram patch maker iRhythm Technologies or blood sugar monitor makers DexCom (DXCM) and Abbott Laboratories (ABT) are taking their devices beyond the clinic. "In the sensor world, people started on the consumer side and wanted to get into health care," said Kevin Sayer, chief executive of Decon Medical. "In health care, we're trying to be more consumer oriented, and I think all of those things are sort of colliding." Early bets favored the tech giants, with every health-related announcement from Apple, Google or Samsung Electronics hitting medical tech stocks. But changing doctors' practices will also require sustained investment in clinical trials. Big tech companies have cut back on investments in health care. Now it seems that medical technologists will be at the vanguard of the digital health revolution - with smartwatches and smart rings bringing them more customers who need to be diagnosed. Blake Goodner, co-founder of Bridger Management, a hedge fund focused on health care, said: "A group of medtech companies focused on digital health are maturing and reaching a scale where they can not only be profitable but also make investments to compete with larger tech companies." Tech giants aren't getting out of the health business. Apple's smartwatch has an electronic heart rate sensor that generates a single-point electrocardiogram, a wrist temperature sensor, and an accelerometer that can detect violent falls. Hundreds of millions of people are wearing smartwatches with health features from Apple or its rivals Samsung and Garmin.
