The abrupt changes in CCTV and Xinhua's behaviour in disclosing such news previously considered highly classified could be due to global miliatry events in 2025 and also Trump's expansionist ambitions (Greenland, Canada, Panama cannal, Venezuela and Western Hemisphere), his unpredictary personal behaviour and willingness to commit US militaries which previous US administration won't undertake.
Whether H20's appearance in 2026 is real or not, IMO China is using this news as opportunity to pass a message to Trump on China's new nuclear deterance option. A show of force will deter and avod giving a false impression that China is weak or unwilling to commit forces when threatened.
And also don't forget Japan's PM's talks on to intervene in Taiwan AR.
On purely military hardware side sans global politics, we need to wait and see if this news is true or not.
