The university has launched two briefs after bringing to a close a PR framework that included Tayburn, Tangible and Clayton Graham.
The first covers work across Hong Kong, India, Singapore and North America, while the second is digitally focused and covers both the UK and abroad.
Mark Sproul, head of digital at the university, said the two briefs overlapped.
'Internationalisation is a big objective for us now in two ways. Firstly, on an recruitment level to attract students from abroad, but also in terms of delivering our courses overseas. A lot of our digital work has an international flavour and it's a cost-effective way of building brand awareness.'
The first brief covers both media relations and public affairs work and is split into lots covering a two-year period. The work includes publicising a university-affiliated photo shoot in New York and encouraging Singaporean students to study the university's courses.
The digital brief, meanwhile, is also split into lots and covers everything from app development through to digital strategy.
Most of the lots across both briefs are for a minimum of two years.
