Wanyama captained Kenya against Nigeria last week when they lost 1-0, and he remains in his homeland for a World Cup qualifier with Malawi later this week.
The 21-year-old talked to Kenya's national TV station NTV about his Celtic future as he is continually linked with a move to England.
"I still have a contract with Celtic and I am their player," he said. "If anything comes up and it is good for me and the club, from there I will move on."
Asked whether he is in talks with any English Premier League sides, he added: "At the moment there are some things, some talks going on.
"But I am concentrating with the national side and I have left that with my agent and I have not contacted him.
"I will find out what's going on when I get back," added Wanyama, who is likely to be forced to sit out the Malawi game due to a leg injury.
