North Korea fired the ICBMs at highly lofted angles in July to reduce ranges and avoid other countries.
While Putin reiterated Moscow's opposition to new sanctions against North Korea, he told reporters he had assured South Korean President Moon Jae-in that Moscow condemns North Korea's nuclear test and thinks it "flagrantly violates" worldwide law. "It should stay calm and avoid taking measures which may raise tension".
Administration officials said on Thursday there remains ample room for additional economic pressure on North Korea.
"There are real concerns North Korea might not be able to be deterred", the official said.
Russian President Vladimir Putin has called for talks with North Korea, saying sanctions are not a solution.
South Korea's military said it was keeping close tabs on the North amid speculation it could stage a missile launch or another nuclear test to mark the 1948 establishment of the Democratic People's Republic of Korea. Pyongyang likely views its arsenal as a guarantee against its overthrow. On the possibility of North Korea-US dialogue, Trump said, "Maybe we'll have a chance to negotiate with somebody else, but I don't put my negotiations on the table, unlike past administrations".
Noting that Trump and President Moon Jae-in had pledged to use all means available to apply maximum pressure to North Korea, the official stressed that the two leaders had promised to strengthen the allied South Korea-US military force. It is unclear if China will back further sanctions. Its sixth nuclear test on Sunday prompted the United States to speak about a "military response" and South Korea to conduct major military exercises.
If Russia leaves the North to do as it likes for fear of the possible deterioration of their relationship, it may fall into bigger trouble in a nuclear domino effect.More news: Destiny 2 Nightfall Strike Details Revealed For Release Week

In Washington, President Donald Trump reiterated Thursday that military action is "certainly" an option against North Korea, as his administration tentatively concurred with the pariah nation's claim to have tested a hydrogen bomb.
Step by step, one goes a long way.
The leaders of South Korea and Japan are holding talks with Putin in Vladivostok on the sidelines of a conference on economic development of Russia's Far East.
Moon showed commitment to the tripartite cooperation of the South and North Koreas and Russian Federation, and Putin strongly supported it. "Certainly that's not a first choice, but we'll see what happens".
He called for it to be resolved through a road map proposed by Moscow and Beijing.
Seoul needs to pull Russian Federation away from the North and China by getting its honest intention across and getting involved in the development of the Far East and other economic projects.
The draft resolution includes a full ban on exports of oil to North Korea, a full ban on textile imports from North Korea, a ban on North Korean laborers generating earnings overseas, and the asset freeze, which will also target members of the ruling worker's party, the diplomat said, calling it a "hard-hitting, ambitious resolution".
One of the first steps to take will be to strengthen communications and economic cooperation with Russian Federation.
