The General Motors Corporation has decided not to exhibit its products at the 1930 Paris Automobile Salon, Oct. 2-12, it was learned yesterday. The company alleges discrimination by the French show officials against American automotive manufacturers.

The announcement was made in the name of James D. Mooney, vice president of the General Motors Corporation and president of the General Motors Export Company, who now is in Europe.

The company has been exhibiting at the Paris show for eleven years, the statement said, adding that for the past five the French have been enforcing a ten-year-old rule under which Americans are permitted to select space only after the manufacturers of every other nation have chosen theirs. Usually the only space left, the company's statement asserts, is poorly lighted and in inconspicuous spots. In addition, the statement declares, show officials have seized many petty occasions to assess fines against American exhibitors.

Company representatives quoted Mr. Mooney as saying:

"It is only proper that each country will, and should permit its own manufacturers to draw for space first. No objection ever has been raised to this practice."

"Individual American manufacturers and the National Automobile Chamber of Commerce frequently have made requests for changes in the French rules to place the United States on a parity with other countries, without result."

"Under the circumstances, the General Motors Export Company regretfully feels it can no longer condone such discrimination, or with self-respect lend its financial and moral support.'"

The withdrawal of General Motors eliminates six makes of passenger automobiles, two truck and two bus lines from the Paris show.
