Putin, who was sharing a platform with South Korean counterpart Moon Jae-in and Japanese Prime Minister Shinzo Abe, has spent the past few days pushing for negotiations, calling on all sides to dial down rhetoric.
If they do not, LKP chairman Rep. Hong Joon-pyo said, "We will have to search for our own new way to deal with North Korean nukes".
"I would like to say that Russian Federation is still willing to implement trilateral projects with the participation of North Korea", Putin told media, in a translation provided by the Kremlin. If they have to take mitigation steps in the region, it could fuel unrest with the regime in Beijing, at which point their concerns over unrest and escapees in North Korea would take a very distant backseat.
Moon said his nation was increasing pressure on Pyongyang in the hope of achieving a diplomatic and peaceful resolution to the crisis.
"It is obvious that the Korean problems can not be settled with sanctions and pressure alone", Putin said.
Jung said the time has arrived for Seoul to consider an "all-out" change to its North Korea policy.

South Korea's defense ministry says the remaining launchers for a US missile defense system deployed to the country will be installed Thursday, in the wake of North Korea's latest nuclear test.
South Korean media reports that a North Korean ICBM has been spotted on the move, and South Korea's Prime Minister said that "some believe North Korea may launch another intercontinental ballistic missile (ICBM) on the 9th; this time at an ordinary angle", according to CNN. The yen strengthened on Lee's remarks.
North Korean leader Kim Jong Un then called the launch a "meaningful prelude" to containing the US Pacific island territory of Guam and called for his military to conduct more ballistic missile launches targeting the Pacific Ocean.
(Korean- ) "South Korea needs to secure regional safety, and the USA needs to protect its troops on the Korean peninsula with the missile defense system".
On coming to power in May, Moon opposed the early installation of the shield.
The US detecting an unannounced missile heading towards the mainland from North Korea could cause a nuclear retaliation that would leave Pyongyang little more than a pile of dust, so Pyongyang would likely try to aim the missile elsewhere.
The South Korean President reportedly told Putin that the concerned parties "must intensify the severity of the UN Security Council sanctions more to bring the North to the path of dialogue".
Russian Federation and China both share a border with North Korea.

In a telephone conversation with Mr Putin on Monday, he urged Russia's support for stronger sanctions against North Korea, such as cutting off oil supplies and banning the use of exported North Korean workers who are seen as a key foreign currency source for Pyongyang.
According to a draft resolution seen by Reuters on Wednesday, the United States wants the United Nations Security Council to impose an oil embargo on North Korea, ban its exports of textiles and the hiring of North Korean laborers overseas, and subject leader Kim Jong Un to an asset freeze and travel ban.
The U.N. Security Council is expected to vote on a new set of sanctions soon.
The bid for the toughest penalties yet against North Korea comes despite renewed warnings against such moves by the leaders of China and Russian Federation, which have veto power in the Security Council. "President Xi would like to do something".
"We will not be putting up with what's happening in North Korea", Trump told reporters Wednesday after the conversation. But the word "dialogue" was not mentioned in the two leaders' telephone call.
