What is the difference between (contract manufacturing) and (outsourcing)?

I cant get the difference I think they both mean the same thing.

here is the definition for both of them from my book :

international outsourcing: parts and products once made locally in the US by American companies are now being made offshore (overseas) or near-shore (in Mexico and Central America) Leeds to loss of jobs locally.

local outsourcing: use of local suppliers within the US to provide parts and services.

contract manufacturing: companies that specialize in manufacturing entire products, not just parts, under contract to other companies.

if you could give example in each one, I would be grateful.
