Hi, 

Are these Chinese sentences correct? Or how would you say it? 

在大中华区以及亚太区市场内开辟新的业务市场。
加强品牌与大中华区以及亚太区市场建立的关系。

I want to say "Matchmaking brands with Greater China as well as the Asia-pacific market" or "Strengthen the relationship between brands and Greater China and the Asia-pacific markets" or "Open up new business markets in Greater China and the Asia-pacific region" 

Thank you in advance.
