Other military changes or innovations that could be attributed to Wu include expanding military exchanges with foreign countries, especially the US, and enabling the longest journey of the navy's friendly flotilla.
The military exchanges with foreign countries were highlighted by those with the US. During Wu's term, senior defense officials began to fly to the US to attend advanced courses.
Wu made several trips to other countries including the US, diplomatic allies in Latin America and Singapore.
He was the first minister of defense to visit the US since the severing of diplomatic relations between the two countries in 1979, but the trip was categorized as a private one and its significance was overshadowed by a trip to the US by his successor, Tang Yao-ming.
As a man who shuns the grandiose, Wu accomplished a lot during his term as minister, with few even noticing.
