I doubt this has anything to do with the KWG halt, but I wouldn't be surprised if the next big investment by the Chinese will be in the ROF.

My bet for the halt is that KWG and NOT have merged...extremely material news for KWG. From an investment point of view, not material enough for NOT, so doesn't warrant a halt, but extremely material from a land assembly perspective if they are able to pull off this merger off.
Just my two cents.
