You shouldn't be happy just because your enemy saying that you are scary.
According to the article
"The two reactors being built on Changbiao are closed fuel cycle nuclear breeder reactors. They produce plutonium. That plutonium could be reprocessed and used as a fuel source for other nuclear reactors. It could also be used to produce nuclear warheads, a lot of nuclear warheads, and produce them very quickly"
"China has stopped annual voluntary declarations to the International Atomic Energy Agency [IAEA] on its stocks of civilian plutonium in 2017"
Hmm looks like China will take the plutonium route to increase her nuclear warheads stockpile
Aljazeera is a generally anti-China media, an Arabic CNN. You should take its article with a truckload of salt. The two reactors (7 and 8) in Tianwan are evolved variant of design that has been sold to Finland, Egypt etc. It is just ordinary PWRs. Any change from a PWR design to a breeder design is NOT improvement but totally new design.
You can clearly see what the author is going to, the old "China threat" story from USA.
