Sandu thanked Poland for acting as Moldova’s "advocate" within the EU and said her country wanted to attract more Polish investment.
Nawrocki said Poland backed Moldova’s reforms and its westward course, adding that the support would not change.
The talks focused on security, education and historical memory, reporters were told.
Nawrocki announced plans to send economic and historical missions to Moldova and said Poland would offer expert support from its Institute of National Remembrance (IPN).
"Moldova has managed to defend democracy," Nawrocki said, referring to recent parliamentary elections in which the pro-European PAS party, founded by Sandu, defeated pro-Russian forces.
Sandu said Moldova had ended its complete dependence on Russian gas following Moscow’s invasion of Ukraine, with Polish support playing a key role.
She added that Russia had spent the equivalent of around 2 percent of Moldova’s GDP attempting to interfere in last year’s parliamentary elections.
Joining the EU is the clearest guarantee of "security, democracy and freedom," she said, noting that an EU report recognised Moldova as having made the most progress among the candidate countries last year.
Sandu also said Moldova wanted to expand trade and attract Polish investment in areas including agriculture, industry, IT, construction and the digital economy.
Later on Monday, she met Poland’s Prime Minister Donald Tusk and parliamentary Speakers.
