Many people on these forums noted that Europeans had little to offer to Asian societies, while they imported many goods unavailable in Europe. That is not entirely correct. What Europeans offered vere service - the trade itself. They created trading net ranging from Basra to Japan, effective on the level which has not been achieved ever before. (It is during this period when Silk Road definitely lost in importance, and Central Asia became impoverished.) Europeans realized 90% of their turnover in Asian seas alone. Imports to Europe were marginal in volumes.
Sorry, but I have to intervene this misleading statement here. There was a vast and well-structured commercial network in the Indian Ocean long before the European arrival. There were numerous commercial cities and entrepots around the circumference of the ocean, from Mozambique to Java. There was a flourishing trade carried by Arabs, Persians, Swahili, Gujuratis, Malays, Chinese, etc.
The Portuguese arrival killed that trade by military means, pure and simple.
Their whole advantage rested purely on naval artillery. Although that technical advantage was only temporary (Indian cannon eventually caught up), there was just enough time for them to violently destroy the entire shpping network in a few short years, and ensure it would never recover. Once the major trading centers (not being fortified) were leveled by shore bombardment and patrols set up, the Indian Ocean trade shriveled. They imposed a monopoly on all navigation on the Indian ocean. A ship couldn't set sail anywhere in the Indian Ocean without a Portuguese license ("cartaz"), and all cargo was subject to seizure.
As to their trading skills, they had next to none. They came as pirates and raiders, under the command of nobles and knights, who wouldn't know a viable trade good if they saw one, and whose entire idea of negotiation is "Do what I say!". They had no notion of how markets operated, they imposed monopoly restrictions treaties with fixed-price guarantees by force of arms, and stole cargoes from local merchants. Where previously there had been ample competition and free trade across the Indian Ocean, it now became a "closed sea" (
marum clausum.) where the Portuguese, and only the Portuguese and nobody else, European, African or Asian, could enter.
Of course, they had next to nothing to offer but cash (silver). Over time, they began replicate (poorly) the prior trade system. But, by my own estimates, the volume of inter-Asian trade replicated by them was considerably less than it had been before.
This didn't change. In the entire 16th C., the trade volume fluctuated, but there was no significant sustained increase. Fleet and tonnage sizes remained more or less stable until the end of the century. They kept hemorrhaging silver to Asia like there was no tomorrow. And the methods didn't change when others came. When the Dutch and English arrived in the 17th C., they operated on the same logic - piracy, raiding, bombardment, imposing monopolies - but much of it now against each other.
In short, your assumption that the Europeans "brought" trade to Asia is a bunch of dogswopple. It was a vast flourishing commercial area, they shut that trade down by naval power. What they replaced it with was an inferior network, tied up in idiotic Medieval restrictions. This gave them dominance, but not much else. They became the only ones who traded in the Indian Ocean because they deliberately forced out the competition violently, not because they were any better at it.
