Two strings can be nonlocally entangled in the same way as two particles can be nonlocally entangled. However, as a single string is nonlocal by itself, there is an additional form of nonlocality in string theory - an entanglement between different parts of the string.
The hidden-variable formulations of quantum mechanics make this entanglement nonlocality manifest. The most successfull hidden-variable theory is the Bohmian interpretation. For the case of strings see

But can string theory bring a new explanation of this nonlocality? In
http://arxiv.org/abs/hep-th/0512186
it is suggested that the Bohmian interpretation can be DERIVED from string theory, so in this sense the answer could be - yes!
