Genetically Modified Food: New Hidden Trouble in Sino-U.S. Relations

In February 2014, Singapore's *Lianhe Zaobao* published an article titled "Genetically Modified Foods: The New Hidden Dangers of Sino-US Relations," summarizing key developments in the ongoing dispute between China and the United States over genetically modified (GM) agricultural products. The article highlights how this issue has become a growing point of contention in bilateral trade relations. At the end of 2013, China returned over 600,000 tons of U.S. corn and related products, citing concerns over the presence of MIR162, a genetically modified trait not yet approved by Chinese authorities. The Chinese government claimed that the imported corn contained unapproved GM components, while the U.S. argued that this move was a form of trade protectionism or retaliation. This incident marked another chapter in the long-standing conflict over GM food regulations between the two countries. This is not the first time that GM food policies have led to trade disputes. In 2001, after China joined the World Trade Organization (WTO), many Americans anticipated a surge in agricultural exports to China. However, shortly after, China introduced strict regulations on GM crops, including the "Regulations on the Safety Management of Agricultural Genetically Modified Organisms" in May 2001, followed by labeling and import safety measures in 2002. These rules significantly restricted the entry of GM soybeans and corn, which were widely used in the U.S. agricultural sector. As a result, China’s regulatory framework created technical trade barriers that impacted American agricultural exports. To prevent further escalation, both sides engaged in multiple rounds of consultations, eventually reaching a compromise to avoid a full-blown trade war. However, tensions resurfaced in late 2013 when China continued to reject shipments of U.S. corn containing MIR162, despite pressure from Washington. During the U.S.-China Joint Commission on Commerce and Trade, officials from both nations held discussions on the issue of GM corn. Despite these talks, China remained firm in its stance, with Chen Xiaohua, Deputy Director of the Ministry of Agriculture, emphasizing that the country would conduct thorough assessments of all GM products and maintain no set timeline for the commercialization of GM foods. Given the complex nature of the dispute and the strategic importance of agricultural trade, this issue is expected to remain a significant challenge in Sino-U.S. relations. Food security remains a top priority for China, and the GM food debate reflects broader domestic concerns. The safety of genetically modified technology has been a global topic of discussion for over two decades, but in recent years, public debate in China has intensified. The rapid expansion of GM foods in the country, combined with the government’s decision to commercialize GM staple crops, has sparked widespread controversy. Additionally, frequent food safety incidents have heightened public anxiety, making the GM issue even more sensitive. The ongoing dispute underscores not only the economic stakes involved but also the deep-rooted concerns about health, regulation, and sovereignty. As both nations navigate these challenges, the future of their agricultural relationship will likely depend on finding a balance between innovation, safety, and mutual trust.

CBN Cutting Discs

CBN abrasive is mainly used for steel parts, such as high speed steel, die steel, 45 steel, etc., can be made into electroplating CBN, resin CBN, sintered CBN. Can be made into grinding wheel, cutting pieces, grinding head. Abrasive sharp, high temperature resistance, good thermal stability, wear resistance. The hardness of CBN is higher than that of ordinary abrasives and the ability to maintain shape is one of the main characteristics of high performance abrasives. CBN is very resistant to pressure. CBN has good thermal conductivity and can achieve cold cutting during grinding.

strong wear resistance, long life

The grinding ratio of CBN wheel can reach 3500-5500, which is 100 times higher than that of ordinary corundum wheel and 3-5 times higher than that of diamond wheel.

environmental protection, no pollution, energy saving and consumption reduction

No too much powder dust.

High work efficiency and good comprehensive economic benefits

The grinding is sharp, the grinding force is small, the dressing cycle of CBN wheel is long, the dressing amount is less, and the replacement time is long. Long service cycle, high grinding ratio, can obtain better economy, good shape retention in use, do not need to change and trim grinding wheel often, save working hours, improve working conditions, is conducive to machining operation.

Cubic boron nitride is not suitable for grinding hard metals and non-metallic materials. At high grinding temperature, CBN will react with alkaline aqueous solution. CBN grinding wheel will decompose in alkaline solution at 300℃, and can decompose in trace amount in boiling water, which will destroy the crystal shape of grinding grains. Therefore, oily coolant should be used instead of water-based coolant during grinding.
