Brazilian President Luiz Inacio Lula da Silva on Saturday was again at odds with Europe over Ukraine while pressing his first European tour since resuming office in January.

The veteran left-winger is seeking to revive his country's diplomatic ties after four years of relative isolation under his far-right predecessor Jair Bolsonaro, but tensions have been on display with the West over Ukraine.

On Saturday, Lula again called for a "negotiated" settlement between Kyiv and Moscow more than a year after the Russian invasion.

The Brazilian leader has angered Ukraine by saying Kyiv shares blame for the war and has not joined Western nations in imposing sanctions on Moscow or supplying ammunition to Kyiv.

"While my government condemns the violation of Ukraine's territorial integrity, we support a negotiated political solution to the conflict," Lula told journalists after meeting Portuguese President Marcelo Rebelo de Sousa in Lisbon.

"We urgently need a group of countries to sit round a table with both Ukraine and Russia," Lula said.

"Brazil does not want to take part in this war. Brazil wants to create peace."

- 'Different position' -

Rebelo de Sousa said: "President Lula believes the road to a just and lasting peace implies making negotiation a priority.

"Portugal has a different position. We think that for a road to peace to become a possibility, Ukraine must first have the right to respond to the invasion."

Portugal is a founding member of NATO and was among the first European countries to supply tanks to Kyiv.

Lula, a 77-year-old former metalworker who served two previous terms as president from 2003 to 2010, has resisted taking sides over the conflict, neither with Europe and the United States, nor with China and Russia.

He raised hackles earlier this month by saying Washington should stop "encouraging" the war by supplying weapons to Kyiv.

He also said the United States and the European Union "need to start talking about peace.

"If you don't talk about peace, you contribute to war," Lula insisted on Saturday.

- Envoy to meet Zelensky -

After a flurry of criticism from Europe, Kyiv and the White House, which accused him of "parroting Russian and Chinese propaganda", Lula said on Tuesday that Brazil "condemned" the Russian invasion.

On Friday, he announced he was sending top foreign policy advisor Cesar Amorim to meet Ukrainian President Volodymyr Zelensky in Kyiv, after representatives of the Ukrainian community in Portugal met the Brazilian delegation in Lisbon.

"Brazil is determined to contribute to fostering dialogue and peace, and an end to this conflict," the Brazilian government confirmed.

Rebelo de Sousa's comments on Saturday were the second in days that took aim at Lula, who was recently named on Time magazine's list of the world's most influential people.

"Brazil's position at the United Nations has always been the same -- on the side of Portugal, the United States and NATO," the Portuguese head of state said earlier this week.

"If Brazil changes its stance, that's none of Portugal's business. We will stick to our views and we will disagree."

Despite their failure to see eye to eye on Ukraine, Lula and Portugal's Socialist Prime Minister Antonio Costa hailed a first summit between the countries in seven years.

Lula revelled in a "special visit marking the relaunch of our bilateral dialogue" after signing a dozen accords in fields including energy cooperation, education and tourism. On Tuesday, he is due to address Portugal's parliament.

The Brazilian leader's trip to former colonial power Portugal will be followed by a two-day visit to Spain to meet King Felipe VI and Prime Minister Sanchez.
