HONG KONG, Nov. 4 (Reuters) — China's Acting Foreign Minister, Chi Peng‐fei, denounced India today for what he described as her continued expansion of “armed aggression against Pakistan” and implied that India was acting with the support and encouragement of the Soviet Union.

Mr. Chi was speaking at a Peking reception given by the Mauritanian Ambassador on his country's independence day. [Indian diplomats walked out as Mr. Chi made his remarks. Agence France‐Presse reported.]

“Recently, because of the daily intensification of India's subversion and aggression against Pakistan, the tension on the subcontinent is becoming even more serious and causing increasing anxiety,” Hsinhua, the Chinese press agency, quoted Mr. Chi as having said.

“In the past few days, the Indian Government, supported and encouraged by social‐imperialism and flagrantly disregarding opposition by Pakistan and condemnation by international opinion, has continued to expand its armed aggression against Pakistan,” he said, ac cording to the agency.

Social‐imperialism is the term used by the Chinese to describe the policies of the Soviet Union.

Without referring to Prime Minister Indira Gandhi by name, Mr. Chi said that an Indian leader had openly demanded that Pakistani troops withdraw from East Pakistan.

“Is this not a brazen demand for Pakistan to give up its own territory, to be occupied by Indian troops?” the minister asked. He said that this demand had completely revealed India's “expansionist ambitions.”

“We strongly condemn India for its subversion and aggression against Pakistan and reaffirm that the Chinese Government and people firmly support the Pakistani Government and people in their just struggle to defend their state sovereignty and territorial integrity and oppose foreign aggression,” Mr. Chi added.
