"Token" is an adjective that means something is not very much and/or may not be important, and may only be for show or effect. So if a country gives 1% of its gross national product to foreign aid, some people might criticize that as a "token contribution." It's also used to describe people of different races or nationalities or gender: if someone is the only woman working in a department, she may be described as "the token woman" (you can use the same language for Asians, gay people, the disabled, or any other group that's typically in a minority—companies will hire one or two to make their workplaces look "diverse").
