A Togo international, he helped them reach the 2006 World Cup, their first World Cup ever. He further scored the team's first ever World Cup goal in a loss to South Korea. The goal was also Togo's only goal scored at the World Cup in Germany in 2006. Kader's star rose in his home country after he scored the late winner in the 1998 African Cup of Nations match against Ghana, thus securing Togo’s first ever win at the tournament. The forward later played in the 2000 and 2002 editions, as well as featuring in Togo's disappointing campaign in Egypt in 2006. On 13 June 2006, he made history by scoring Togo's first ever World Cup goal in their first group match against Korea Republic, with a well taken finish.
