There was a polio outbreak in China in 2011 that was traced back to Pakistan. Prior to that outbreak, the last case of polio in China had been in 1999. The outbreak was contained after 21 confirmed infections plus another 23 suspected. The Chinese public health system mobilized 1000 health workers, spent $26 million, and vaccinated 44 million people. If we can't get rid of polio in Pakistan and Afghanistan, then this will just keep happening.
