Magnus Jacobsson, a member of the Swedish national legislature, declared that he presented the candidacy of the Trump administration and the governments of Kosovo and Serbia “for their joint work for peace and economic development, through the cooperation agreement signed in the White House”.
"Trade and communications are important building blocks for peace," he added in a statement.
Pressed on social media about whether the deal was substantial, Jacobsson said it was "unbelievably good" to see the parties sit down and sign an agreement after 20 years of open conflict.
"For my part, I hope it is the beginning of a process that can result in a peace agreement and mutual recognition," he added.
Trump oversaw the landmark agreement in Washington last week. The deal revolved around Serbia and Kosovo agreeing to normalize their economic relations.
The countries were caught in a conflict that led to Kosovo declaring its independence from Serbia in 2008.
The president's adviser on Serbia-Kosovo, Richard Grenell, told reporters that the deal would not have been possible without Trump's "outside" perspective.
"All the experts in Washington said that 'we are not talking about recognition, we are not talking about this as a symbolic word,' what we try to do is ignore that and from an outside perspective, go in and dig deep," Grenell said.
A Norwegian lawmaker, Christian Tybring-Gjedde, nominated Trump for the Nobel Peace Prize earlier this week.
Tybring-Gjedde said Trump's role in another landmark agreement, between Israel and the United Arab Emirates, prompted his presentation.
"As other Middle Eastern countries are expected to follow in the footsteps of the United Arab Emirates, this agreement could be a game changer that will turn the Middle East into a region of cooperation and prosperity," the lawmaker wrote in the letter to the Norwegian Committee on the Nobel Prize.
The agreement establishes the normalization of economic relations between the Governments of Kosovo and Serbia and the opening of their embassies to the State of Israel in Jerusalem, a policy promoted by the White House, in contrast to the majority of the world that does not recognize the city like the Israeli capital.
In 2018, the same legislator Tybring-Gjedde, proposed Trump for the Nobel Peace Prize for the summit in Singapore between him and Kim Jong-un, leader of North Korea, which reduced nuclear tensions in Asia.
A spokesperson for the Nobel committee told reporters that it could not comment on the reported nomination, citing a confidentiality clause.
Submissions for the 2020 Nobel Prize closed in January. The 2021 award will be announced next October. Will Trump win it this time?
