London, Jan 29 (Agencies): Pakistan is aggressively expanding its nuclear arsenal in order to counter India’s definite edge in conventional warfare, according to media analytical reports. 

Pakistan is worried about India's fast growing economy and population. Although the numbers of nuclear weapons held by either country are small, the nuclear competition between the two countries is reminiscent of the Cold War arms race between the US and USSR, The Telegraph said. 

India’s warring machine is now largely geared against the Chinese threat, Pakistan remains focused on India.

Since it is not able to match India's defence expenditure, economy and population, Pakistan has relied on nuclear technology since the 1970s to provide itself a cushion of sorts.

The latest escalation in tensions - with Pakistan saying it wants to maintain parity of stocks with India, which last year unveiled a nuclear-powered submarine - will come as no surprise to analysts, the report said.

Diplomatic cables released by whistle blower website WikiLeaks have also provided snippets of information on Pakistan's nuclear programme.

In a memo dated December 2008, Peter Lavoy, an intelligence officer briefing NATO’s Permanent Representatives on Afghanistan and Pakistan, stated that despite looming economic meltdown, "Pakistan was producing nuclear weapons at a faster rate than any other country in the world".

Cables also suggest that analysts believe Pakistan is concentrating on developing smaller, mobile nuclear devices to counter India's conventional battlefield forces, and so need more fissile material, the report said.
