The decision was taken at a meeting of the National Command Authority (NCA), who controls the nation's nuclear programme, Dawn reports.
The meeting was presided over by Prime Minister Nawaz Sharif, the report added.
Although the country is facing a severe economic crisis, the decision to strengthen its nuclear power comes amid worsening regional security situation and discriminatory policies within the non-proliferation regime.
Earlier also, Pakistan had developed short-range and low-yield tactical weapons in response to India's cold start doctrine.
However, the NCA reiterated its commitment towards avoiding arms race, remaining engaged with the Nuclear Security Summit process and playing its part in the global non-proliferation regime.
According to the report, the offer of sharing its expertise under IAEA safeguards and training personnel on nuclear security were also renewed.
