Las Palmas did not reveal the transfer fee for the 28-year-old Gran Canaria native, although club president Miguel Angel Ramirez admitted that they could not match the money on offer in China.
“On signing his contract they are offering him seven million euros ($8.6m) net, and what we can’t do is ruin the life of one of our own,” Ramirez said in a press conference.
Spanish press reports suggested the deal could be worth upwards of 20 million euros to Las Palmas, while the Spanish side revealed they would receive 30 percent of any future transfer of Viera as well as potential bonuses.
However, Las Palmas, who are currently fighting against relegation from La Liga, also revealed that Viera had signed an agreement to return to the club should he cut short his stint in Asia.
Viera, who started his career at Las Palmas and then returned in 2015 after spells with Valencia, Rayo Vallecano and Standard Liege, won his first cap for Spain earlier this season.
