Referring to the US, Foreign Minister Sergey Lavrov said today that "the one who is smarter and stronger must take the first step" in diplomatic efforts.
Lavrov says Moscow has asked Washington in confidential conversations if it realizes that US allies South Korea and Japan would suffer the most if the North's nuclear missile tests provoke a military conflict.
He says the US response was that certain developments would leave military intervention as the only option.
He was speaking with students at Russia's top diplomacy school.
