Prime Minister Atal Bihari Vajpayee on Sunday charged Pakistan with acquiring weapons and blaming New Delhi for triggering off an arms race in the subcontinent.

"Whatever steps India is taking, it is for self-defence. We are not in any arms race with anybody. Those who are themselves acquiring weapons are blaming us," Vajpayee said in New Delhi on his return from an eight-day visit to Indonesia and Thailand.

PM in Southeast Asia: The Complete Coverage

Asked about the achievements of the National Democratic Alliance government, the PM said, "To assess our performance is the job of the people and the media is also involved in it. Four years have passed and that is sufficient. It is itself important that a coalition government has completed four years. Because there has been a feeling that if at all a coalition government is formed, it will not run for long."

On the allegations levelled by former Uttar Pradesh chief minister Mayawati against his family members, the PM said, "I have already expressed sadness on that statement."

He denied that the government had interfered in the functioning of the Central Bureau of Investigation, which had conduced raids on Mayawati's residences.

Asked whether Chhattisgarh Chief Minister Ajit Jogi, who was chargesheeted by the CBI in a forgery case, should resign, he said, "It is up to his inner conscience and what ideals the Congress wants to establish."
