Sent 4: Later, the strategic location and deep-water channel close to the coast brought in the bigger vessels of the trade-wind traffic crossing the Indian Ocean.
Sent 5: The first to realize the larger commercial potential, as so often throughout the country's subsequent history, were the Chinese.
Sent 6: In 1409, under a new directive from Emperor Chu Ti to pursue trade in the South Seas and the Indian Ocean, a Chinese fleet of 50 ships headed by Admiral Cheng Ho called in at Melaka.
