The Chinese embassy in Poland has also asked Warsaw to "effectively ensure the legitimate rights and interests, and humanitarian and safe treatment of the person involved."
A Polish man was also arrested for alleged espionage along with Wang on Tuesday. Both men are suspected of having "worked for Chinese services and to the detriment of Poland," said Polish special services spokesman Stanislaw Zaryn.
He said their apartments and workplaces were searched, adding that the Polish suspect had worked "for several state institutions".
The arrest of Wang is the latest setback for Huawei.
Following her arrest two Canadians were detained in China on grounds of national security, in what has largely been seen as retaliation for the case.
The incident has also sparked a surge of patriotism in China with companies encouraging staff to buy Huawei smartphones -- and several companies even offering employee subsidies to buy phones from the home-grown company.
Huawei in December said it expects to see a 21 percent rise in revenue for 2018 despite what it called "unfair treatment" around the world, as several countries have banned Huawei telecommunications technology.
Last month, Britain's largest mobile provider BT said that it would remove Huawei equipment from its cellular network after the foreign intelligence service called the company a security risk.
