In exchange for Thai agricultural products, not only rice, but also rubber. Thailand's Minister of Transport previously revealed that the core of the Memorandum of Understanding between the Chinese and Thai Governments on Intergovernmental Cooperation Projects for the Development of Railway Infrastructure in Thailand and the Exchange of Agricultural Products in Thailand is that Thailand tries to use agricultural products to pay for some products and services invested by China's high-speed rail, including Thai rice and rubber. However, he also said that this memorandum is not a mandatory treaty, but only a framework agreement for Sino-Thai high-speed rail cooperation, and the details are still to be agreed by both parties. After the signing of the memorandum on high-speed rail between China and Thailand, the two sides will establish a working group to further discuss the specific details.
