Where did you get those 'facts'. Remington Arms is owned by Cerberus Capital Management. Howa is part of a major Japanese manufacturing conglomerate and has no links to Remington or Cerberus, nor has it ever had.
The Howa / Smith & Wesson / Mossberg 1500, Weatherby Vanguard plus now it seems the Webley & Scott Empire Rifle barrelled actions are all Howa products, in fact different grades of a single product. They are made and sold as barrelled actions in various versions, calibres, barrel weights / lengths and their purchasers choose and procure a variety of stocks to give a large range of models. Foremost amongst them is the US importer Legacy Sports International. ('Our' Howas are all LSI procured and stocked, Highland Outdoors Limited being a secondary purchaser.)
The Howa 1500 action is not a Remington 700 copy or clone. It actually has more Sako L series features than Remy. Taking the two actions out of the riflestocks shows a machined flat action bottom on the Howa with an integral recoil lug whilst the 700 is round having been made out of drawn tubing and uses a separate lug that has to be fitted between action and barrel reinforce on assembly. Trigger assemblies are not interchangeable. Key components have different dimensions and the Howa even uses a different thread on the action to barrel tenon joint ... etc, etc.
The only thing they have in common is the same action-top profile and screw hole sizes / spacing so scope mounts are interchangeable. Oh and they are twin-lug Mauser system bolt-actions. (But so are many competing designs that nobody calls a 700 clone - eg Savage and Winchester actions.)
There are many 'Remington clones' around, many of them limited production custom jobs. That reflects the range of aftermarket goodies produced for the 700s in recent years. Make an action with the same external shape as the 700 and trigger hanger arrangements and huge ranges of stocks and improved trigger assemblies are available. That reflects Remington 'glory years' when almost all US custom rifles up to and including out and out benchrest pieces started with a 700 action. Those days are long, long gone and have nothing to do anyway with the comparative merits of these two quite different factory rifles.
