Question regarding distribute ELB angular website to other region (Asia)

I have an angularjs website running on ELB node.js server, and is load-balanced. The region I choose is Ohio, our users in Aisa simply can not open the website. However, I have a java backend api running on ELB load balancer in Ohio region as well, exactly the same setup, my Aisa user is able to query the api. I am wondering why, and how to make my angular website accessible to other part of the world.

Additionally, I have a static website (a landing page), I used S3+Cloudfront to distribute to all edges with no problem, but I felt my heavy duty angular website should not go this route.

Please advise, please also advise on the cost if possible, thanks!
