Answer:
How will e-commerce affect Emerson's ability to export products from China?
Step-by-step explanation:
The answer above is the least relevant question that Emerson should think about before taking the decision of either building the facility in China or in the United States.
The reason is that exporting goods that are ordered online, from China to the United States, should not represent any significant problem, since the United States already imports billions of dollars in goods from China every year (the United States has the largest trade deficit in the world, with China precisely).
The Chinese economy is built for exporting. What Emerson should decide is the city where to locate the facility. Ideally, it should be a city with good infraestructure like Shanghai or Shenzhen.
