US VICE President Mike Pence was snapped giving Vladimir Putin a cold stare at a summit, as he reportedly warned him not to meddle in American elections.

Putin said he and Pence spoke on the side-lines of the Association of Southeast Asian Nations conference in Singapore, discussing arms control and other issues.

Pence and Putin "discussed the upcoming G20 Summit and touched on the issues that will be discussed when President Trump and President Putin are both in Argentina for the summit," according to the vice president's press secretary, Alyssa Farah.

The G20 Summit will be held in Buenos Aires at the end of November.

An NBC reporter tweeted: “New per the @VP’s Office—> The VP’s office says Vice President Pence directly addressed Russian meddling in the 2016 election in a conversation with Vladimir Putin on Thursday in Singapore.

“The conversation took place following the plenary session this afternoon at ASEAN.”

Pence reportedly told NBC he wasn't in a position at the dinner to say more.

He said: “Well we really didn't have the opportunity; he was literally across a broad table.

“Look, we've been very clear about this administration's commitment to ensure, whether it be Russia or other countries, that there's no tolerance for meddling in our elections.”

He also mentioned that the US had taken “decisive action” to protect the integrity of the ballot box.

He added: “I know the president has also made that very clear in his meetings with the president in the past.”

Putin and Pence have planned another meeting due in a few weeks.

Putin said Moscow and Washington need to discuss the future of the 2011 New START arms-reduction agreement and the situation around the 1987 Intermediate-Range Nuclear Forces treaty.

Trump has stated his intention to withdraw from the INF.

The INF treaty is a 1987 arms control agreement between the US and the Soviet Union – now the Russian Federation.

It eliminated all nuclear and conventional missiles, as well as their launches, with ranges of 500-1,000km (310-620 miles) short range, and 1,000-5,500km/620-3,420 miles, intermediate-range.

But, the INF treaty didn’t cover sea-launched missiles.
