We have to view this piece as a bit of an anti-Chinese propaganda, reminiscent of the so-called "Yellow Peril" of the British Empire colonial days.

The article sheds no light on how such expensive key components find their way into a besieged Ansarullah-governed Yemen.

Further, the article sidesteps the huge complexities involved in increasing the range of the warhead carrier by a massive 500 km, unless it's discussing adapting Kheibar Shekan's maneuvrable warhead to older, longer range carrier vehicles, which would still require Iranian expertise at every level as well as extensive testing.

Overall, we're inclined to call nonsense on this item of news.
