The border between China and Pakistan means little for consumer goods. Asia isn't a small town, but the largest continent in the world. Most industrial centers of China are located in the eastern seaports for easy transportation to the West, Japan, South Korea, and South East Asia. Dutch and German seaports are big and efficient but they aren't exactly for transporation to Moscow. It's that far, and more difficult.
The general rule in this hi-tech world is that where information for consumers merge, prices for consumers are lowest. In South Korea, Seoul is the place to buy almost anything at the lowest possible cost. In Japan, Tokyo. In Asia as a whole, Tokyo, or Hong Kong. In the entire world, the US is the cheapest place. China does have the most number of factory workers and produced items for the IT industry, but this century isn't like 1.5 millenia ago when Tang was the cheapest place for silk because silk was produced there and it took months to years to transport the products to Rome or Arabia or Japan. Right now, the most popular TV drama in South Korea is Hae Shin (Sea God), a story about a sea merchant who defeated pirates and traded silk and other things between Tang, Shin-La, and Japan. One World for all consumers hasn't been achieved even 1,500 years later!
