The Pakistani Government has accused India of escalating the arms race in the region after reports from Delhi that India is planning to test-fire a new long-range nuclear-capable missile later this year.
Both sides have carried out missile tests recently
"India is proliferating its missile program and it is better that the international community pay attention and prevent India from this relentless pursuit of more and more
weapons," Foreign Office spokesman Aziz Ahmed Khan said.
Indian Defence Minister George Fernandes was quoted as saying on Sunday that Delhi was developing a longer-range version of its nuclear-capable Agni missile and was keen to test-fire it this year.
Both countries test-fired short-range nuclear-capable missiles in March.
In 1998, the two countries carried out nuclear tests, drawing sanctions and criticism from around the world.
Tit for tat
Pakistan and India have carried out tit-for-tat missile tests several times in recent months and have also expelled several of each other's diplomats.
The nuclear rivals have fought three wars since 1947 and came to the brink of
conflict again last year.
India has not publicly stated the range of the new Agni III's missile. Analysts say it could be greater than 3,000 kilometres
The Agni II, could reach targets more than 2,000 kilometres (1,200 miles) away in Pakistan and China.
The Agni missiles are part of an arsenal that includes the Trishul surface-to-air missile and the Prithvi missile, with a range of 150 km and can carry a one-tonne nuclear payload.
Pakistan's Abdali surface-to-surface missile has a range of up to 200 km.
