preparing reports and planning to set up small but more commercial nuclear power plants indigenously. In June 2008, the Pakistan Government announced plans to build commercial nuclear power plants III and IV commercial nuclear power plants at Chashma, Punjab Province, each with 320–340 MWe and costing PKR 129 billion, 80 billion of this from international sources, principally China. A further agreement for China's help with the project was signed in October 2008, and given prominence as a counter to the US–India agreement shortly preceding it. Cost quoted then was US$1.7 billion, with a foreign loan component of $1.07 billion. In March 2009, SNERDI announced that it was proceeding with design of CHASNUPP-III and IV, with China Zhongyuan Engineering as the general contractor. The PAEC said Beijing was financing 85% of the US$1.6 billion project. Contracts for CHASNUPP-I and II were signed in 1990 and 2000, before 2004 when China joined the Nuclear Suppliers Group (NSG), which maintains an embargo on sales of nuclear equipment to Pakistan, but there are questions about China's supply of Chasma-3 and 4. On 24 September 2010, China informed the IAEA that it will implement an agreement with Pakistan on the export of two nuclear reactors for Islamabad's Chashma nuclear complex. Beijing has said that the reactor deal is part of a 2003 agreement between the two countries, a claim many have questioned, though Germany has accepted. These will be the third and fourth reactors at the complex. According to the Chinese communication to the IAEA, the reactors will be placed under international safeguards. Concerns have been expressed over the lack the safety features incorporated into the Chashma-3 and Chashma-4 reactors, which are alleged to use a design which is not considered safe enough to build in China. In March 2013, Pakistan and China agreed to build a 1000 MW CHASNUPP-5 at Chashma Nuclear Power Complex. In July 2013, it was announced that Pakistani officials were considering approval of KANUPP-2, a 1,000 megawatt reactor to be built with assistance from China. According to PAEC, CNPS hosts four nuclear power plants based on Chinese Pressurized Water Reactor (PWR) technology. CNPGS Unit 1 (C-1) and Unit-2 (C-2) have a gross capacity of 325 MW each. C-1 started operation in 2000, while C-2 in 2011. CNPGS Unit 3 (C-3) and Unit-4 (C-4) both with gross capacity of 340 MW each started commercial operation in 2016 & 2017, respectively. All
