Mr. Speaker. last June in London I talked with H. P. Chou. second secretary of the Chinese Peoples Republics diplomatic delegation in the United Kingdom. Our conversation lasted for an hour and 20 minutes and took place at his Embassy on Portland Place. I wanted to find out why the Chinese government. a short time previously. had refused a visa to Averill Harriman and why their journalists had not applied for entrance to the United States. My dealings. I add. were "contact not contract." to use HUBERT HUMPHREYS phrasing of the distinction insisted on by the Logan Act. I had long been interested in the proposed exchange of journalists and its bogging down.
