From the Document: "H.R. 7314 would require the Department of State to assess and report periodically to the Congress on China's support for Russia's recent war against Ukraine. On the basis of information about the costs to prepare similar reports, CBO [Congressional Budget Office] estimates that satisfying that requirement would cost less than $500,000 over the 2022-2026 period. Such spending would be subject to the availability of appropriated funds."
