China is set to launch its first joint archaeological project in South America, following an agreement between Chinese and Peruvian institutions to study the ancient Caral civilization. The move marks a new milestone in the country's growing overseas archaeological cooperation.
The Institute of Archaeology of the Chinese Academy of Social Sciences, Peru's Caral Archaeological Zone under the Ministry of Culture, and the Professional School of Archaeology at the National University of San Marcos signed a cooperation agreement on Saturday to conduct research on the ancient Caral civilization.
The Caral civilization, which is considered to be the oldest civilization discovered in the Americas, emerged along Peru's northern coast and dates to around 3000 BC to about 1800 BC.
The project marks China's first joint archaeological initiative in South America, expanding its overseas archaeological footprint to four continents: Asia, Africa, Europe and South America. It also encompasses cooperation with Belt and Road partner countries, major centers of ancient civilizations and regions crucial to the study of human origins.
For Chinese archaeologists, the project represents a new step in overseas archaeological engagement and international cooperation, fostering mutual learning and dialogue among civilizations, Chinese experts said.
Cooperation beyond borders

In recent years, Chinese institutions have participated in a series of overseas archaeological projects, from exploring ancient cities along the Silk Road to studying early civilizations in Africa and Central Asia.
They not only brought Chinese expertise and talent, but also advanced Chinese technologies, equipment and solutions, experts said.
In February, a significant archaeological breakthrough has emerged from Mit Rahina in Giza, the site of ancient Memphis in Egypt, where a joint Chinese-Egyptian mission has uncovered a limestone structure believed to be connected to the temple of King Pharaoh Apries from Egypt's 26th Dynasty (664-525 BC), according to the Xinhua News Agency.
Zhang Hai, head of the Chinese team and an archaeologist from Peking University, told the Global Times in a previous interview that the Chinese contingent applied distinctive methods for documenting and recording finds, while deploying Chinese-developed technologies such as the "4D kankan Meta" 3D scanner for precise, real-time topographic and sectional modeling, plus specialized software for capturing dislocated stone elements in 3D to aid future digital restoration and preservation.
In the latest China-Kazakhstan joint archaeological project, Chinese equipment and technologies played an important role in the team's discoveries.
Building on the excavation, the archaeological team used drones and the "I Survey" mobile field documentation system to conduct systematic surveys around the excavation area. The survey covered more than 10 burial grounds and documented more than 50 Pazyryk-era tombs.
Pazyryk culture flourished from the late sixth century BC to the third century BC, Shao Huiqiu, a professor at the Collaborative Research Center for Archaeology of the Silk Roads, Northwest University, told the Global Times.
According to Shao, who is the Chinese lead for the China-Kazakhstan joint archaeological project, none of the tombs had previously undergone formal excavation, giving them significant research potential. The use of these technologies has enabled the team to carry out more efficient and comprehensive surveys of the area,
During the China-Kazakhstan joint archaeological project, archaeologists have recovered a number of important artifacts, including human remains, pottery, gold foil pieces, horse bones and iron horse equipment.
The finds have provide valuable material evidence for studying the burial practices, funerary customs and material culture of the Pazyryk culture in the Lake Markakol region, said Shao.
Researchers also conducted regional surveys around the excavation area, documenting more than 50 Pazyryk-era tombs.
Through the joint archaeological project, China and Kazakhstan have gained a deeper understanding of Bronze Age to Early Iron Age archaeological remains in the Lake Markakol basin, according to Shao.
In 2027, the two sides will continue excavations at key sites and burial grounds identified during the survey, while advancing regional archaeological investigations, data analysis, multidisciplinary research, young archaeologist training and academic exchanges.

Archaeological exchanges
China's overseas archaeological cooperation has also become a platform for broader exchanges among researchers and civilizations.
Such projects, experts say, are helping expand archaeological research beyond national borders and provide new perspectives on exchanges among ancient civilizations.
China's overseas archaeology has grown alongside its broader participation in global cultural heritage protection.
The National Cultural Heritage Administration's cultural heritage development plan through 2030 calls for expanded archaeological cooperation in Austronesian-speaking regions, trans-Himalayan areas, and routes connected to the Silk Road and Maritime Silk Road, reported Xinhua.
The plan seeks to strengthen the methods used to trace Chinese cultural artifacts overseas, and advance efforts to retrieve lost cultural relics.
It also pushes for greater Chinese participation in global cultural heritage governance and expanded international partnerships, including new protection cooperation agreements with more countries worldwide, according to Xinhua.
In these joint collaborations, researchers from different countries bring together their expertise in regional archaeology and fieldwork, conducting exchanges on archaeological surveys, excavations, multidisciplinary research and regional cultural studies. Such cooperation has strengthened mutual learning and laid a foundation for long-term partnerships, according to Shao.
The China-Uzbekistan cooperation has established research centers in Samarkand and Termez to support studies on human-environment interactions and cultural heritage. The initiative has also trained professionals in Silk Road archaeology, scientific research and heritage conservation through programs for Uzbek universities and research institutions, while promoting international academic exchanges to advance Silk Road heritage protection and cultural cooperation, noted Zhu Jiangsong, a member of the China-Uzbekistan joint archaeological team from the School of Cultural Heritage, Northwest University.
Through these partnerships, Chinese archaeologists are not only contributing technology, research experience and training, but also gaining first-hand materials and fresh perspectives that help advance the study of ancient civilizations and enrich China's archaeological research.
。人们需要水来喝，农作物需要水来生长，甚至制造火箭燃料返回地球。因此，缺乏可用的液态水是人类登陆火星的主要障碍。但是火星上有很多冰。美国宇航局的一项新研究表明，我们可以在冰上钻孔，以获得足够的水来维持火星上的人类生命。去年，在火星表面下发现了冰川，这一重大发现为第一批宇航员登陆火星提供了“取之不尽，用之不竭”的水。研究人员说，在火星上的8个地方发现了地下冰川，有些位于地表以下几英尺（1米）的深处，还有一些位于地表以下100米或更深处。研究人员分析了火星勘测轨道飞行器收集的数据，发现地下冰川的成分“几乎是纯冰”。美国宇航局的一项研究模拟了钻冰和融化冰从冰川中取水的过程。德克萨斯州航空航天公司（Aerospace Corporation）的高级执行官斯蒂芬霍夫曼（Stephen Hoffman）领导的研究人员说：“火星表面曾经有很多水，但现在人们一致认为火星表面非常干燥。几项研究表明，火星的许多地方都有丰富的水资源，包括那些被认为是人类在火星上登陆的替代着陆点的地方。如果这些水资源可以用于载人登陆火星，那么执行这些任务的方式将发生巨大变化。
