No country has yet sent a person to Mars. The US and USSR have successfully landed robots on Mars but only the American ones were really a success. The Soviet lander stopped transmitting after 15 seconds. Only the US, USSR, and Europe have successfully put a probe into orbit around Mars. India send an orbiter to Mars, costing only 67 million dollars!
