Is soju haram? A drink from Korea that contains alcohol

In my country, *there is* a halal soju, but it said in an article if the factory made it halal by doing something (Adding something or so I'm not sure). But, is it still haram since it contains alcohol? I mean for general soju. And from what I saw on Korean dramas, they are intoxicating (I'm not sure if they drink another drink). Do you have a reliable source or reference or your own opinion about this drink? I couldn't find the information about it, hope I can get the answer here. Thanks.
