I had the similar problem in one of mine projects.
If I got you correct, you have website in many languages. For example:
And on Chinese website for specific url: www.website.cn/page-url
you want to show content from page: www.website.com/page-url
I am not sure if it is possible to do with code. But you can achieve it with rewrite rules and reverse proxy (IIS URL rewrite module & IIS ARR module). Just setup rewrite rule for url: www.website.cn/page- url rewriting content from www.website.com/page-url
