Writing in Vietnam’s Communist Party newspaper Nhan Dan, he said the country’s neutral foreign policy shows “a pragmatic way to solve the crisis”.
He will hold talks with Communist Party general secretary Nguyen Phu Trong and new president To Lam on Thursday.
The US embassy in Hanoi condemned the visit and said: “No country should give Putin a platform to promote his war of aggression and otherwise allow him to normalise his atrocities.”
It was the Russian president’s second state visit on his tour of Asia following his stay in North Korea where he and Kim Jong Un agreed on a “comprehensive strategic partnership pact“.

Putin and Kim sign new defence deal
The agreement is said to cover investment, strengthening cultural ties and cooperating on health, medical education and science, but also contains a mutual defence clause.

North Korea’s KCNA news agency clarified the clause later on Tuesday and said the countries agreed to provide all available military assistance if the other side faces “armed aggression”.
Putin called it a “breakthrough document,” while Kim noted North Korea and Russia’s “fiery friendship” and said the pact was their “strongest ever treaty”. He then vowed full support to Moscow against Ukraine.
US secretary of state Antony Blinken regarded Putin’s visit as one made “in desperation, to develop and to strengthen relations with countries that can provide it with what it needs to continue the war of aggression that it started against Ukraine”.
Koo Byoungsam, spokesperson of South Korea’s unification ministry, said Seoul was still interpreting the results of the summit.
But Japan’s chief cabinet secretary said Tokyo has “grave concerns” as Putin did not rule out cooperation with North Korea on military technology.
It follows accusations that North Korea has supplied Russia with weapons for its war in Ukraine, which both Pyongyang and Moscow deny.
They also insist that the deal struck on Tuesday is intended to be peaceful.
New pictures show the moment of impact as an Israeli missile hit a Beirut apartment block and exploded.
The block was one of five buildings destroyed by airstrikes on Friday alone.
Israel launched airstrikes in the southern suburbs of Beirut in a fourth consecutive day of intense attacks.
There were no immediate reports of casualties.
An Associated Press photographer captured a sequence of images showing an Israeli bomb approaching and hitting a multi-storey apartment building in Beirut’s Tayouneh area.
Richard Weir, a senior crisis, conflict and arms researcher at Human Rights Watch, reviewed the close-up photos to determine what type of weapon was used.
“The bomb and components visible in the photographs, including the strake, wire harness cover, and tail fin section, are consistent with a Mk-84 series 2,000-pound class general purpose bomb equipped with Boeing’s joint directed attack munition tail kit,” he told AP.
Deadly strikes as bombardment stepped up
Israel stepped up its bombardment this week – an escalation that has coincided with signs of movement in US-led diplomacy towards a ceasefire.
The Israeli military said its fighter jets attacked munitions warehouses, a headquarters and other Hezbollah infrastructure. It issued a warning on social media identifying buildings ahead of the strikes.
Meanwhile, an Israeli airstrike killed five members of the same family in a home in Ain Qana in the southern province of Nabatiyeh, Lebanon’s state media said.
The report said a mother, father and their three children were killed but didn’t provide their ages.

Three other Israeli strikes killed six people and wounded 32 in different parts of Tyre province on Friday, also in south Lebanon, the report said.
Video footage also showed a building being struck and turning into a cloud of rubble and debris that billowed into Horsh Beirut, the city’s main park.
More than 3,200 people have been killed in Lebanon during 13 months of fighting between Israel and Hezbollah – most of them since mid-September.
About 27% of those killed were women and children, according to Lebanon’s health ministry.
Israel dramatically escalated its bombardment of Lebanon from September, vowing to cripple Hezbollah and end its barrages in Israel.
Friday’s strikes come as Lebanon’s caretaker prime minister has asked Iran to help secure a ceasefire in the war between Israel and Hezbollah.
The prime minister appeared to urge Ali Larijani, a top adviser to Iran’s supreme leader, Ali Khamenei, to convince the militant group to agree to a deal that could require it to pull back from the Israel-Lebanon border.
Iran is a main backer of Hezbollah and for decades has been funding and arming the Lebanese militant group.
On Thursday, Eli Cohen, Israel’s energy minister and a member of its security cabinet, said that prospects for a ceasefire with Lebanon were the most promising since the conflict began.
The Washington Post reported Israel’s Prime Minister Benjamin Netanyahu was rushing to advance a Lebanon ceasefire to deliver an early foreign policy win to his ally, US President-elect Donald Trump.
“Super high-IQ revolutionaries” who are willing to work 80+ hours a week are being urged to join Elon Musk’s new cost-cutting department in Donald Trump’s incoming US government.
The X and Tesla owner will co-lead the Department Of Government Efficiency (DOGE) with former Republican presidential candidate Vivek Ramaswamy.
In a reply to an interested party, Mr Musk suggested the lucky applicants would be working for free.

“Indeed, this will be tedious work, make lost of enemies & compensation is zero,” the world’s richest man wrote.
“What a great deal!”
When announcing the new department, President-elect Donald Trump said Mr Musk and Mr Ramaswamy “will pave the way for my administration to dismantle government bureaucracy, slash excess regulations, cut wasteful expenditures, and restructure federal agencies”.
Mr Musk has previously made clear his desire to see cuts to “government waste” and in a post on his X platform suggested he could axe as many as three-quarters of the more than 400 federal departments in the US, writing: “99 is enough.”
