"Since its independence in 1991, Uzbekistan has been working with the government of the United States to dismantle and decontaminate the sites where the Novichok agents and other chemical weapons were tested and developed"
What, actually, is your point, if any? Novichok class weapons were developed in Uzbekistan under top secrecy for years. It was only later, after the defection of Mr Mirzayanov later that the nature of the programme came out. Plainly the Soviet Union, and later Russia, have illegally hoarded their supposedly banned weapons, just as they have aided Assad to do the same in Syria.
