Belgian zookeeper Eric Domb and his team have been in state of what could be described as pandemonium for months as they prepare for two pandas scheduled to arrive in spring.

Domb said he is working round the clock to build a cozy home for the "China ambassadors" and guarantee that the special guests lack for nothing over the next 15 years, the allotted time span agreed by the governments in September for the animals to stay in Belgium.

"We feel huge responsibility to host them and see them breed," Domb said in his office as he held photos of the four-year-old pandas, Hao Hao and Xing Hui.
