Which two countries are set to resume direct flights to strengthen business ties?

The correct choice highlights the significant development in the relationship between India and China, reflecting an effort to enhance business ties through the resumption of direct flights. This move is particularly important as it facilitates easier travel for business leaders, investors, and tourists, thus creating opportunities for increased trade and collaboration.

Resuming direct flights between these two countries also indicates a step towards thawing relations that may have been strained in previous years due to border disputes and geopolitical tensions. The ability for business professionals to travel directly without the need for layovers may help stimulate economic cooperation and foster a more positive diplomatic environment.

In contrast, while other pairs of countries listed might have their own business connections, the resumption of direct flights between India and China specifically highlights a strategic objective to bolster economic ties, which is crucial for the economies of both nations given their significant positions in the global market.
