There's no way to use military force on a CEO corp.
Ainz - the first thing I'd do is send a message to the corporation owner and ask them if they'd transfer their corp to another country. You can increase the tax rate (or threaten to) to make your country a less attractive place to have a corporation in. If they don't answer or refuse to move then the only thing you can do is to nationalise the corporation, or bid on it with your own enterprise so that it becomes yours. Be careful with this though, such hostile actions have been known to be the start of trade wars and even military wars.
In your country settings you can switch on and off the "Block CEOs". As far as I know, this setting will stop CEOs building, buying or moving corporations into your country but won't do anything against enterprise corporations that are already there. If you want to build, buy or move corporations of your own enterprise into the country, you'll have to toggle the "Block CEOs" setting while you do your business moves then reblock afterwards.
Like Johanas said, I'm also of the opinion that CEO corps are more of a positive than a negative for your country. Everyone has to play their own game though.
Hope this helps,
