In remarks reported by CNBC, Trump said he was planning to discuss the plan with film industry leaders. “I’m not looking to hurt the industry, I want to help the industry.” He added: “So we’re going to meet with the industry. I want to make sure they’re happy with it because we’re all about jobs.” Trump also took aim again at California state governor Gavin Newsom, saying the film industry “has been decimated by other countries taking them out, and also by incompetence, like in Los Angeles, the governor [Gavin Newsom] is a grossly incompetent man, he’s just allowed it to be taken away from”. Trump added: “Hollywood doesn’t do very much of that business, they have the nice sign, and everything’s good, but they don’t do very much.” Trump’s talk of film tariffs makes no sense, but it’s already doing damage – to Hollywood Peter Bradshaw Peter Bradshaw Read more Newsom responded with a statement saying: “Governor Newsom continues to champion California’s iconic film and television industry – recognising it as a cornerstone of the state’s economy, one that sustains hundreds of thousands of good-paying jobs across every sector around the state.” “His plan to more than double the state’s film and television tax credit reflects a commitment to keeping production here at home, supporting workers and maintaining California’s global leadership in entertainment. If the President announces a proposal with more details, we will review it.” Newsom had earlier responded to Trump’s announcement by proposing a $7.5bn federal tax incentive scheme, saying in a statement to Variety: “Building on our successful state program, we’re eager to partner with the Trump administration to further strengthen domestic production.” Tax incentive schemes in the US currently operate on a state-by-state basis, and Newsom had announced a plan in April to boost California’s to $750m. California senator Adam Schiff also condemned Trump’s tariff proposal while backing calls for a federal tax credit scheme, saying in a statement: “Blanket tariffs on all films would have unintended and potentially damaging impacts, [but] we have an opportunity to work together to pass a major federal film tax credit to re-shore American jobs in the industry.” Late night TV hosts Jimmy Kimmel and Jimmy Fallon also joined the chorus of dismay and bafflement at Trump’s plan. Commenting that Trump was “now aiming his wrecking ball at Hollywood”, Kimmel questioned whether foreign-made movies were a “national security threat” as Trump claimed. “I don’t care where they’re made. I really don’t. I guess it’s what the late, great Hannibal Lecter would’ve wanted. Sonic, the illegal immigrant hedgehog, is a national security threat and he must be stopped!” Kimmel also mocked actor Jon Voight’s role in Trump’s thinking, saying: “This is where he reportedly got the tariff movies idea – from Angelina Jolie’s 86-year-old father she won’t talk to. What a great idea. Next year, The White Lotus is gonna be set at a Hampton Inn.” Fallon also took aim at Trump’s implication that foreign locations were somehow taboo, saying: “Gonna be fun seeing the next Lord of the Rings filmed in Bayonne, New Jersey,” adding: “If you don’t like that, you can also watch Emily in Des Moines [instead of Emily in Paris]. It’s just as charming.” Explore more on these topics Film Film industry Donald Trump Trump tariffs Gavin Newsom Jimmy Kimmel Jimmy Fallon news Share Reuse this content Most viewed Live German parliament votes again on Merz’s bid to be chancellor after humiliating first round – Europe live Trump and Carney to meet at White House in closely watched encounter Mushroom lunch’s sole surviving guest details deadly meal and its aftermath as trial of Erin Patterson continues ‘It’s the misogyny slop ecosystem!’ How Candace Owens and the American right declared war on Blake Lively Wisconsin woman missing for more than 60 years found ‘alive and well’

In a single domesticated grain seed, one might see the bud of great civilizations. The birth of agriculture was a turning point in humans' social development, as stable food supplies enabled people to transcend the constraints of food gained by hunting and gathering. After that, people were able to settle down and experience population booms. As one of the major areas around the globe where agriculture originated, China has contributed to the world's domesticated rice, millet, buckwheat and soybeans. Archaeological studies have unveiled that the planting of rice originated around 10,000 years ago in the lower reaches of the Yangtze River, leading to the eventual replacement there of hunting and gathering practices dating back 5,000 to 6,000 years. "It marked the formation of a rice-based agricultural society in the area," said Zhao Zhijun, an archaeologist at the Chinese Academy of Social Sciences. Archaeological studies of the origins of rice-based agriculture are an important part of a national project tracing the origins of Chinese civilization itself. President Xi Jinping has greatly valued the project. At a group study session of the Political Bureau of the Communist Party of China Central Committee on May 27, 2022, Xi, who is also general secretary of the CPC Central Committee, emphasized the significance of the project and the role that archaeological studies play in better understanding Chinese civilization. The project to trace the origins of Chinese civilization, in addition to finding signs of human activity more than 1 million years ago, has also proved that China's history includes 10,000 years of culture and more than 5,000 years of civilization. The project has provided clear knowledge of the origins and formation of Chinese civilization, the history of its development, the process of the formation and development of its pluralistic and integrated pattern, and the characteristics of the civilization and why it was formed in such a way, he added. This was not the first time that Xi emphasized the importance of the origin-tracing project. Since the 18th National Congress of the CPC in 2012, Xi has toured more than 100 historical and cultural locations and issued many instructions related to archaeology and the origin-tracing project. During the 23rd group study session of the Political Bureau of the CPC Central Committee in 2020, Xi called for giving more attention to archaeological research and letting historical facts speak for themselves. "This will provide strong support for our efforts to carry forward the best of traditional Chinese culture and increase our cultural confidence," said Xi. The origin-tracing project has been carried out since 2002. Its ongoing fifth phase, which started in 2020, involves the participation of more than 500 researchers from 29 institutes across the country. It primarily centers on several ancient capital sites, including the Liangzhu site in Hangzhou, Zhejiang province, the Taosi site in Xiangfen county, Shanxi province, the Shimao site in Shenmu, Shaanxi province, and the Erlitou site in Luoyang, Henan province, from 3,500 to 5,500 years ago, as well as other settlements mainly along the basins of the Yellow, Yangtze and Liaohe rivers. The project has also expanded to a wider geographic and chronological framework to decode how Chinese civilization emerged and how its diverse elements formed a unity. Excavation of the Liangzhu site, which is over 5,000 years old and is one of the major sites covered in the origin-tracing project, has yielded an inner city covering 3 million square meters and an outer city of 6.3 million sq m, making it the world's largest capital at the time. It also had a giant water control system, which contributed to the formation of a rice-based agricultural society. By calculating the earthwork volume, archaeologists found that building the entire ancient city, the water control system and Mojiaoshan — a 10-meter-tall man-made terrace in the center of the city — required 10,000 people working daily for seven-and-a-half years. The discoveries show that Liangzhu had a kingship able to organize people for large-scale public construction, and its social differentiation, emergence of the city concept and existence of a kingship prove that it became a civilized society, said Wang Wei, a veteran archaeologist at the Chinese Academy of Social Sciences. Significant topic Wang said that tracing the origins of a civilization is a significant topic in the research of human history. Over the years, the Chinese project has provided China's answer to how to define civilizations. In 2022, Xi commended the efforts and stressed that the project has made creative contributions to the research on tracing the origins of the world's civilizations. Wang said: "International academia has proposed three indispensable elements for a civilized society based on features of Mesopotamian and Egyptian civilizations: written characters, metallurgy and the city concept. But we can find that some of the three elements were absent in many ancient civilizations. For example, the Mayan civilization had no metallurgy, while the Incan civilization didn't have written characters." Western scholars believe that Chinese civilization began with the Yinxu Ruins in Anyang, Henan province, a capital of the late Shang Dynasty (c.16th century-11th century BC), based on the discovery of inscribed oracle bones from that time. However, Chinese archaeologists don't agree. With continued archaeological research, international academia now believes that places around the world can propose criteria for civilization based on their own ancient social development. China's archaeological studies have shaped the nation's criteria in defining a civilization: the development of productivity, an increase in population, the appearance of cities, social differentiation and the emergence of kingship and state. "These criteria are suitable for identifying other civilizations as well," said Wang. "Civilizations have in common the appearance of kingship and state. They are only different in the ways of imposing kingship and the forms of state." In China, kingship and state "were shown by exquisite jade and bronze ritual artifacts, grand palaces and magnificent mausoleums imitating aboveground palaces", he added. "In Mesopotamia and ancient Egypt, they were demonstrated through superb stone temples, pyramids and large-scale tombs." Multidisciplinary subject President Xi said in 2020 that archaeologists should work closely with researchers from other fields to make an interpretive analysis of material remains. Zhang Chi, a professor of archaeology at Peking University, said that since material remains are often the research focus of archaeological studies, these should not only be observed with the eyes, but also studied using scientific and technological tools. Therefore, from the perspective of research methods, archaeology is by nature a multidisciplinary subject, Zhang added.
