A senior Russian official has told NHK that President Vladimir Putin is considering proposing a revival of the six-party talks on Pyongyang's nuclear program when he meets North Korean leader Kim Jong Un on Thursday.
Russia has reportedly informed the United States and China of its intention to make the proposal.
Putin and Kim will hold their first summit in Vladivostok. Kim is expected to arrive by train in the city in the Russian Far East on Wednesday.
The summit is likely to feature a wide range of topics, including the denuclearization of the Korean Peninsula and bilateral economic cooperation.
The six-party talks were chaired by China and started in 2003. The other participants are the US, North Korea, Japan, South Korea and Russia.
But the US and North Korea became increasingly at odds over how to verify Pyongyang's commitment to scrap its nuclear development program. The talks have been stalled since December 2008.
Putin has been saying that North Korea's nuclear issue should be discussed in the six-party framework.
Putin is believed to be trying to increase Russia's involvement in the matter.
