China has emerged as a global leader in the development of AI world models, with its thriving real-world application ecosystem powering both technological advancement and commercialization, said a top Chinese AI researcher.
Against the backdrop of the ongoing 2026 Global Digital Economy Conference, the integrated application of artificial intelligence has become a central focus of industry attention, with physical AI and general world models emerging as key developmental trends.
In an interview with the China Global Television Network (CGTN), Zhu Jun, a professor from the Department of Computer Science and Technology, Tsinghua University, shared his insights on the latest breakthroughs in physical AI and general world models.
"[Large language models] learn primarily from symbolic text data, including natural language and machine language. But world models go much further. They are designed to understand the physical world, and ultimately guide actions within physical world," said Zhu.
When assessing the global landscape of AI-generated video tools, Zhu noted that Chinese players are keeping pace with their international counterparts and are currently standing at the forefront globally.
"In terms of the architecture and conceptualization [of general world models], I believe China and the United States are essentially starting at the same time and exploring in parallel. In many areas, China is keeping pace with the United States. China's large video models are standing at the forefront globally, and some may even outperform certain American models," he said.
To move from a technological edge to a commercial advantage, Zhu streessed that China's vast scenario demands are providing a huge advantage for rapid model iteration.
"Large language models have many favorable conditions for commercialization in China, because our scenario demands are very strong. Take video models as an example. They are developing rapidly in China, and I believe that is closely linked to our advanced content production ecosystem. From AI animated series last year to AI live-action short dramas this year, and now people are paying attention to medium-length and even full-length dramas. These demands are driving our models to iterate quickly. Our scenarios give us a huge advantage," he noted.
Running from Thursday to Sunday in Beijing, the 2026 Global Digital Economy Conference hosts a series of special topic sessions covering artificial intelligence, digital talent development and industrial digitalization, bringing together nearly 40 high-level industry delegations and over 1,000 distinguished guests from across the globe.
China leads development of AI world models: expert
China on Thursday called on the international community to find a home for the Secretariat of the Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas beyond National Jurisdiction (BBNJ Agreement) best positioned for its efficient operation, pointing out problems with the joint candidature by Belgium and Chile.
Chinese foreign ministry spokeswoman Mao Ning made the remarks at a regular press briefing after Belgium and Chile on Nov. 6 announced the decision to join their candidatures for the seat of the secretariat. This joint candidature provides for the secretariat being based in the city of Valparaíso, Chile, the Clearing-House Mechanism (CHM) will be installed in and operating from Brussels, and Brussels will host the meetings of the subsidiary bodies.
Mao said that earlier this year, China nominated Xiamen to bid for the seat of the Secretariat of the BBNJ Agreement, noting that the candidature has quickly received the support of the majority of the Parties to the Agreement.
"By seeking an unauthorized backroom deal on issues that should be determined by the Conference of the Parties (COP), the joint candidature is problematic in at least six aspects," the spokesperson said.
First, it contravenes the stipulations of the BBNJ Agreement. According to the agreement, the seat of the secretariat, the specific modalities for the operation of the CHM, including its installation, as well as where the subsidiary bodies hold their meetings shall all be determined by COP, and the CHM shall be managed by the secretariat, she said.
Belgium and Chile traded under the table what should be collectively determined by all Parties to the Agreement. This is a violation of the stipulations of the agreement and an act of disrespect to the authority of COP, Mao said.
Second, it contravenes procedural justice, Mao said, adding that the choice of the secretariat seat and the development of the CHM are two items of different nature scheduled to be collectively determined by COP through separate decisions.
The Belgium-Chile proposal bundles the two together in an attempt to force it as a package upon other Parties, which is against applicable procedural rules and a hijack of the Parties' will, she said.
Third, it contravenes established international practice. Stressing that the management of the CHM is a key mandate of the secretariat, Mao said in the practice established by other international treaties like the Convention on Biological Diversity, the secretariats and CHMs are located in the same place.
The Belgium-Chile proposal, which locates the Secretariat and the CHM separately across the ocean, will without a doubt raise the operation cost, lower management efficiency, and increase the financial burden on the Parties to the Agreement, Mao said.
Fourth, it contravenes equitable geographical distribution. The vast majority of major global institutions are based in Europe, with none located in Asia. Developing countries have been calling on global institutions to redress this long-existing injustice and bring about greater fairness and equity, the spokesperson said.
She said Brussels is already home to the headquarters of NATO and the EU. "If this non-coastal city were to host the CHM of an ocean-related treaty as well, it would further widen the digital divide to the detriment of the shared interests of the Global South."
Fifth, it contravenes fair competition. Noting the BBNJ Secretariat is tasked with contributing to global ocean governance, and the selection of its seat should be a fair and friendly process in keeping with the rules, Mao said the Belgium-Chile proposal, however, politicizes the bidding process and attempts to divide Parties into camps.
It not only undermines the principle of fair, friendly and healthy competition, but also negates the essence of multilateralism, she said.
Sixth, it contravenes the original commitment. Chile first made the bid citing its significance for the Global South. Yet according to the new proposal, Chile will no longer assume the substantive functions of the secretariat. Belgium, for its part, only seeks to host the CHM and thereby has in effect relinquished its bid for the secretariat seat, Mao said.
Stressing that the adoption and entry into force of the BBNJ Agreement is a victory of multilateralism, Mao said its implementation likewise needs to serve and advance the common well-being of all humanity.
"China firmly supports multilateralism and the cause of the UN, and is committed to promoting and improving global ocean governance. As one of the first signatories and Parties to the Agreement and the largest assessed-contributor to its budget, China has the will, capability and confidence to provide strong support and backing for the operation of the Secretariat. China is full ready. We look forward to working with all Parties to the Agreement to keep selection of the Secretariat seat proceeding in the right direction, and uphold the overall and fundamental interests of the international community, especially those of developing countries," Mao said.
