Final answer:
China lost interest in contacts abroad in 1433 due to various reasons, leading to the decline and abandonment of its naval efforts and a shift towards isolationism.
Step-by-step explanation:
The evidence that indicates China lost interest in contacts abroad in 1433 is that Yung Lo's successor, Zhu Zhanji, decided to disband the naval expeditions initiated by Zheng He and they were never resumed again. There are several reasons that explain this decision, such as:
- The Chinese found nothing in the cultures they visited that they couldn't obtain through trade.
- After Zheng He's death, no admiral of his stature arose.
- Anti-commercialism and xenophobia won out.
These factors led to the decline and abandonment of China's naval efforts and a shift towards a policy of isolationism.
