In describing the battle for medal supremacy between the U.S. and China, writer Mark Sappenfield said the United States "targets overall excellence, trying to qualify as many athletes as possible. China targets winning, focusing a larger share of its efforts on athletes who can take gold. This was clear in the Beijing medal table."

Russia, which has a gold medal in men's judo, and host Great Britain are expected to duke it out for the remaining spot among the top three nations when the medal count is finalized. Great Britain is yet to win any medals in the games, although it's still early.
