NatGeo scored a big hit last year with its Cathay-sponsored documentary on Marco Polo.
Cathay has signed up as the exclusive sponsor of the Zheng He series across NatGeo's regional and Taiwan feeds, the latter broadcasting the documentary in Putonghua.
A photo exhibition in Beijing, Taipei and Kuala Lumpur will be showcasing images
from NatGeo photographer Michael Yamashita, who features in the documentary. NatGeo will also launch a viral email contest to help promote the documentary, which will premiere in December. The grand prize has yet to be confirmed, though is likely it will be sponsored by Cathay.
