The official also acknowledged that foreign-owned companies in Lithuania are facing pressure from China, too.
"Apparently, we failed to fully estimate the whole arsenal of measures that are currently being used by the unpredictable authoritarian state," she told a group of MPs. "And they are being used not only against Lithuania, but against other EU countries as well".
The measures "also target foreign-owned businesses operating in Lithuania," she added.
The vice-minister noted that affected companies are not always willing to share information as they are trying to find ways to either get around the restrictions or to resolve the situation differently.
Neliupsiene stressed that China is not Lithuania's most important trade partner.
Lithuania has angered China by allowing Taiwan to open its representative office in Vilnius under the name "Taiwanese" instead of "Taipei".
In retaliation, China last autumn halted freight trains to Lithuania, stopped issuing food export permits, cut credit limits and raised prices for Lithuanian companies, and removed Lithuania from its customs systems.
