A top EEC official warned Japan about trade policy.

Willy De Clercq, the commissioner for external relations of the European Economic Community, warned Japan against discriminating in favor of the United States in the Asian nation’s latest measures to cut its trade surplus. De Clercq said the Common Market was alarmed that 80% of the $1-billion program unveiled by Tokyo last month to reduce Japan’s trade surplus was intended to benefit American companies. He said the EEC “attaches particular importance” to Japan’s public procurement policy. “Do not discriminate against European companies in your public buying policy,” he said in a letter to Tadashi Kuranari, Japan’s minister of foreign affairs. The letter went out before high-level talks between the EEC and Japan begin Thursday in Tokyo.
