The following is the May 15, 2023, Congressional Research Service report, China Naval Modernization: Implications for U.S. Navy Capabilities — Background and Issues for Congress.
From the report
China’s military modernization effort, including its naval modernization effort, is the top focus of U.S. defense planning and budgeting. China’s naval modernization effort has been underway for about 30 years, since the early to mid-1990s, and has transformed China’s navy into a much more modern and capable force. China’s navy is a formidable military force within China’s near-seas region, and it is conducting a growing number of operations in the broader waters of the Western Pacific, the Indian Ocean, and waters around Europe.
