Cross domain canonical and hreflang

[occasionalpedestiran]

Morning guys,

I am stuck on the best way forward for my international client.

They have multiple domains with their international sites, plus a global site with the .com, eg:
client.com (global)
client.us (USA)
client.co.uk (UK)
client.fr (France)
etc...

A large number of the sites are in English, as is the global site. The global site hosts some of the same content as the local sites, usually published on the global site first an then duplicated on the local sites as an exact replicate.

At the moment there is nothing to indicate to the search engines which version of the content we want to be ranked in each country. Would the best way to do with be with cross domain hreflang, or with cross domain canonical tags?
