Russia and China have called for calm after North Korea test-fired a series of ballistic missiles, while the United States urged North Korea not to aggravate tensions.
North Korea fired seven Scud-type ballistic missiles, with a range of about 500 kilometres.
Russia's Foreign Ministry said in a statement that Russia and China had agreed that all sides should refrain from any steps that could further destabilise the region.
The two countries called for a return to six-party talks aimed at coaxing North Korea to give up its nuclear programme.
A spokesman for the US state department described the launches as "not helpful" and said North Korea should refrain from actions that aggravate tensions and focus on denuclearization talks.
North Korea has fired several non-ballistic, short-range missiles since it carried out a nuclear test on 25 May.
The country is barred by UN resolutions from firing ballistic missile such as the Scud.
