Among the changes you might consider is the Mongol invasions which dominated large areas of Asia for several hundred years. You should also think about the expansion of Buddhism into China and other areas from India, where it became almost non-existent. Also, the rise of Islam in India and the Mughal (Mongol) Empire there. It was an Islamic ruler who erected the Taj Mahal as a tomb for his wife.
Asia as most of the world remained agricultural. However, you should note that the end of the specified time period was the beginning of the period of European expansion which European influence--and interference-in Asia became prevalent.
