The Brazil international has a contract with Tito Vilanova's side until 2015 - by which time he will be 32 years old - and the Brazilian admits he'd be open to offers.
Manchester City have been linked with the diminutive right-back in the past, but opted to sign former-Inter Milan and Alves's fellow Brazil teammate Maicon last summer instead.
And it now seems Alves has not been put off by the experiences of Didier Drogba and Nicolas Anelka in China. The two ex-Chelsea strikers joined Shanghai Shenhua at the end of the last season, but neither enjoyed a happy spell at the club - Drogba returning to Europe to play for Galatasaray while Anelka has signed for Juventus.
Alves said: "I have been there and loved the country. It has progressed well and is improving [in terms of the football]. In life, you can never say never. I am fine at the moment but I cannot rule anything out.
"Doors should always be left open."
The former-Sevilla fullback joined the Catalan club in 2008, and has enjoyed a hugely successful five years at the Nou Camp, winning three La Liga titles, two Copa Del Reys and two Champions League trophies.
With 60 caps to his name for his country, Alves will be hoping to play a key role for Brazil at the 2014 World Cup on home soil.

But preparations for this summer's Confederations Cup got off to an start this month, as Luiz Felipe Scolari's first match in charge ended in a 2-1 defeat to England at Wembley.
