A student rights group in Solomon Islands says the government's ignored those studying in Taiwan when it moved to cut ties with the country.
Taipei ended the 36-year relationship on Monday after Solomon Islands endorsed a move to shift relations to China.
According to students, there are 125 Solomon Islanders studying in Taiwan on scholarships funded by Taiwan's Foreign Ministry.
The leader of student activist group Youths Online Campaign, Maverick Peter Seda, said the government hasn't told students what's going to happen now.
"They should have considered our human rights, which is the right to education because our students at the University in Taiwan, they have the right to education, so they should have considered that right first before making any diplomatic change."
Maverick Peter Seda said some students have received notices to leave their dormitories in Taiwan.
A Solomon Islands government statement on Tuesday says students in Taiwan are being well looked after.
"We never thought this would happen to us, it's like a nightmare," said Lorah Tis George, a fourth-year international relations student at Nangkim University in Tapei.
"We didn't expect any of this to happen and now we're only being worried and depressed of what's going to happen next to our study."
