SECRET 1. VULNERABILITY OF CHINA TO BLOCKADE THE COMMITTEE considered a draft report+ on the vulnerability of China to blockade, together with Minutesø by the Secretary, covering the contribution to the report by the Security Exports Control Working Party, with amendments thereto, all of which had been prepared as a brief for use in discussion with the Americans. MR.
