WASHINGTON, Sept 18 (Reuters) – US Treasury Secretary Scott Bessent plans to discuss AI, trade, rare earths and economic issues when ​he meets with Chinese Vice Premier He ‌Lifeng in New York City this weekend, according to a source familiar with his plans.

The discussions are significant because the US and China are the two major forces ‌driving ​development of advanced AI tools ⁠and the global adoption ⁠of the technology. Rare earths play a crucial role in the manufacturing of technology.

Bessent and He will meet ahead of a summit ​between US President Donald Trump and Chinese President Xi Jinping on September 24 in Washington.

The ⁠Associated Press first reported ⁠the US plans.

Bessent said in a ​statement that he expects the discussions to cover “both open- ​and closed-weight models.”  Open-weight models are AI ‌systems with publicly accessible core elements. Users can download and fine-tune them for specific tasks.

Chinese open-weight models are becoming more popular with US companies ⁠because they can be cheaper than so-called closed-weight AI tools, such as those developed by Anthropic, OpenAI ⁠and other US ‌companies.

Chinese AI models have even ⁠been used by the US government. ​Reuters ‌reported on Thursday that a US ​government website ⁠employed an AI model from a Chinese company to allow users to search proposed federal regulations even though the FBI accused the model’s developer, Alibaba, of “malicious” copying of Anthropic’s technology.
