PEKING, Nov. 7—China called on India and Pakistan yesterday to find a peaceful solution to their frontier dispute, but warned that it would “resolutely support” Pakistan in the event of war.

The warning came in a speech by the Acting Foreign Minister, Chi Peng‐fei, at a banquet marking the completion of talks between Chinese leaders and a Pakistani delegation led by the former Foreign Minister, Zulfikar, Ali Bhutto.

“Our Pakistan fends may rest assured that should Pakistan be subjected to foreign aggression, the Chinese Government and people will, as always, resolutely support the Pakistan Government and people,” Mr. Chi declared.

The warning, coupled with a sharp attack on India for having “crudely interfered in Pakistan's internal affairs” was interpreted here as reflecting a willingness on the part of Peking to extend increased military assistance to Pakistan.
