Implies that samples have been brought illegally into the US

Does the highlighted sentence want to say "although the institute claims that it will not seek intellectual rights over its data and samples, Doujak believes that the institute does not give its samples to others as these samples have been brought illegally into the US"?

Context:

Emerging environmental artists contend with the new landscape of globalization and to threats to ecosystems on a worldwide scale. Ines Doujak’s photo collages, photographs, and multiples deal with the related issues of intellectual property and biopiracy within globalization; she also points to their prehistory within colonialism and their relation to celebrated historical figures, such as the naturalist and explorer Alexander von Humboldt. Her work J. Craig Venter, Master of the Gene (2007) targets Venter, an executive in the Institute for Genomic Research, a corporation that sought to sequence the human genome. Venter is currently engaging in an ocean-exploration genome project or “global ocean-sampling expedition” that charts microbiological marine biodiversity using
his own yacht. Venter has stated that Charles Darwin’s Beagle and another British marine research expedition, the Challenger, inspired this work. While the Institute states clearly that it will not seek intellectual property rights over data collected as part of this global sampling and that that data will be made available “publically to any scientist,” Doujak approaches this work with suspicion and implies that samples have been brought illegally into the US. She
suggests there is a biocolonialist, if not racist, basis to Venter’s project.
