The 30-year-old claimed that the opportunities on offer prompted him to choose a move to the Far East.
"I’m sure I’ll face many challenges here. I like the project to develop this club," he continued.
"It was that which convinced me to come to Hebei, as well as the financial aspect.
"I’m also fascinated by Chinese culture, so to come and play here is definitely an interesting challenge."
Despite the riches he is due to earn in China, the former Napoli forward is aware of the fact his international career is virtually over.
"Yes, it’s likely that experience is over. But I’ve already made the decision to come here and I want to do my best for my new club."
The winger made his international debut in April 2007 against Chile, making 48 appearances and scoring seven goals.
