Cathay Pacific conducts recruitment in multiple locations throughout the globe, and it is therefore necessary for the company to send recruitment personnel to these locations. It stands to reason that the airline will wait until there are a sufficient number of candidates in a particular location before recruiting in that location. So you just need to wait patiently; it might be weeks or months. As the email you received clearly states, you will be contacted, most likely when the airline is recruiting in your area. Most applicants will have received a similar email. It's nothing to worry about.
