The Post discusses China’s lobbying efforts this morning here.

From 2005 to 2009, China for the first time hosted more U.S. politicians and congressional staff members than Taiwan, according to LegiStorm.com, a congressional watchdog. China has also tripled the amount it spends on lobbying firms, including such powerhouses as Patton Boggs and Hogan & Hartson, since 2006 — although it continues to be outspent by Taiwan.

The Foreign Agents Registration Act database at DOJ has documents related to foreign representations, such as this one between Patton Boggs and the Embassy of the Republic of China.
