Of course we care. Any foreign government except fellow outcasts such as North Korea engaging with Pakistan is a serious concern. Not because anything much will come out of it - look at what decades of relations with Saudi, US and China have gotten Pakistan. But because it delays the policy of complete isolation.
Pakistanis are quite happy as long as only 2-3 countries in the world are engaging them - they will pretend that means they are not isolated. That pretense has to end and Pakistan needs to face up to the consequences of incubating terrorism and nuclear proliferation, thereby destabilizing all of South Asia.
