EC APPOINTS NEW TRADE CHIEF The European Community Commission today appointed its chief spokesman, Hugo Paemen, as its top official in charge of multilateral trade negotiations, a Commission spokesman said. Paemen, a Belgian official who had previously been chief aide to former External Affairs Commissioner Etienne Davignon, has been in his post since January 1985. The spokesman said Paemen will continue as chief spokesman until the retirement on May 1 of Paul Luyten, who is now in charge of EC departments handling negotiations in the world trade body GATT, the OECD and other forums.
