Step-by-step explanation:
The Chinese invention that made sea trade possible when conflict happened on land in Central Asia was the compass. The compass was an essential navigational tool that allowed sailors to determine their direction at sea, which was crucial for long voyages and exploration.
This invention, along with others such as the sternpost rudder, gunpowder, and the printing press, were Chinese innovations that found their way to Europe and played a significant role in the era of exploration and empire building.
