On January 26, 2024, the new "Regulations of the State Council on the Standards for Declaration of Concentration of Business Operators" were announced and implemented. The new standards have raised the threshold for operators to apply for concentration of operators to the anti-monopoly law enforcement agency of the State Council. The total global and domestic revenue, as well as the unilateral revenue standards in China, have been raised from the current 10 billion yuan, 2 billion yuan, and 400 million yuan to 12 billion yuan, 4 billion yuan, and 800 million yuan. This eliminates the need for concentration review of business operators for investment and merger transactions that have declaration obligations under the old declaration standards. It is expected that the declaration volume can be reduced by 30%, reducing the institutional transaction costs of investment and merger. This is conducive to further stimulating the vitality of business entities and consolidating and enhancing the economic recovery trend. The competitive environment continues to optimize. The concentration review of business operators aims to maintain fair market competition, create a favorable business environment and innovative development space for various business entities.
