Paolini and Elisabetta Cocciaretto had given the hosts a 2-0 overnight advantage.
Later Saturday, Japan earned a consolation win when Himeno Sakatsume defeated Lucia Bronzetti 7-6 (7/4) 6-2.
Last year's runners-up, the United States – record 18-time competition winners – dragged themselves back into the tie with Caty McNally and Nicole Melichar's doubles win.
Their 6-4, 6-2 success over Magali Kempen and Elise Mertens earned a vital point for the Americans, with Belgium leading 2-1 in Ostend.
The US now have to win Saturday's two reverse singles rubbers to reach September's eight-team finals in Shenzhen, China.
Fighting spirit from Team USA 😤🇺🇸

In Melbourne, Harriet Dart and Jodie Burrage won the doubles rubber to power Britain past Australia.
Later, Emerson Jones pulled a point back for Australia for 3-1 after beating Katie Swan 7-5, 6-3 in Saturday's reverse singles.
Britain started the day with a commanding 2-0 lead after rising star Mika Stojsavljevic upset Talia Gibson and Dart beat Kimberly Birrell on day one.
It left Australia's Storm Hunter and Ellen Perez facing a must-win clash in Melbourne, but they failed to rise to the occasion and crashed 6-3, 6-4.
"That feels amazing," said an emotional Burrage, who has battled injuries in recent times.
"I'm proud of us for the way that we played, way that we came out and managed to close that out."
It was an impressive victory with none of Britain's top four making the long trip with Emma Raducanu, Katie Boulter and Fran Jones opting to focus on the European clay-court season and Sonay Kartal injured.
Seven ties are being played this weekend.
Ukraine, Spain and Kazakhstan also sealed their tickets to the final.
KAZAKH POWER 💪🇰🇿

But Aliona Bolsova and Sara Sorribes Tormo teamed up to win the doubles. Kaitlin Quevedo then rallied past Veronika Erjavec 7-6 (7/4), 6-2 to seal the winning point.
Kazakhstan won 3-1 against Canada after former US Open champion Bianca Andreescu lost her reverse singles tie 7-6 (7/5), 3-6, 7-6 (7/4) to Yulia Putintseva.
Andreescu had pulled Canada level 1-1 on Friday.
But Anna Danilina and Zhibek Kulambayeva beat Andreescu and Cross 7-5, 6-1 in Saturday's doubles.
