In 1986, Pakistan eventually entered in understanding with China when it signed an agreement on peaceful usage of commercial nuclear power technology. In 1989, China announced to sell of the reactor but the nuclear power plant did not operationalise due the PAEC scientists and engineers, who eventually designed the reactor based on CNP-300 in China, and had to conduct several lengthy testing and pass PAEC required regulation phases, since China did not have the experience to sustain such a large and highly complex project— the experience Pakistan learned from running the Karachi Nuclear Power Plant.
