Final answer:
Silk from Tibet and Central Asia is an instrumental material supporting the local and global economy, with the Silk Roads historically facilitating significant cultural and economic exchanges. China's integration with Tibet highlights the strategic importance of the region's resources for industrial manufacturing and global trade.
Step-by-step explanation:
The material from the domestic regions of the mountains of Tibet and Central Asia that provides a strong extension to the fabric of the local and global economy is silk. This region, with its varied geography including high mountain passes through vast ranges such as the Pamirs, is known historically for its contribution to trade routes like the ancient Silk Roads. The trade across these routes significantly supported industrial economies by providing luxury items and resources necessary for manufacturing goods, effectuating a two-way flow of commodities and culture that has profoundly influenced civilizations across regions.
China ensures economic integration with Tibet, as Tibet's raw materials are crucial for China's growing industrial economy. The abundant natural resources found in Tibet's mountains can aid in the manufacturing of goods for global markets. Despite cultural differences, the strategic significance of Tibet and Central Asia in terms of trade and resources continues to impact the economy and political relationships today.
