So again, that is something where I think the last 20 years we've been through this period of optimization and globalisation. Globalisation of supply chains, optimization of return profiles, just in time technology, et cetera, et cetera. This started with discussions around trade disputes between the U.S. and China, but I actually think that the vulnerability of those global supply chains is really being highlighted by this COVID pandemic. It has two important implications as I see it, the first is that we will likely see some certain amount of unpicking of those global supply chains and the move towards regionalization, and we'll also see businesses accept lower profit margins in exchange for greater certainty of supply and product, and consumers are going to have to get used to that as well. So that obviously has important implications for shareholders in terms of returns on equity over the long term, and I think that where that lends itself to is this idea around regional economic centres, as opposed to one large global supply chain global economy is as we see it today.
And what that will really require to be successful is a large central domestic economy within a particular region, that then provides the demand to support the regional hub or the hubs or spokes that serve the hub. And within emerging markets, there's different sets of opportunities and challenges, so clearly China has a very large domestic economy, and so China, North Asia, Greater China with respect to Taiwan, et cetera, and technology investment, I think is one area that remains a significant position in the portfolio and it's an opportunity going forward. I think markets that rely more on global trade to drive their own investment domestically are potentially more challenged, so South Africa, as a country in particular within emerging markets, which yes, has a certain size of domestic economy, but relies on external trade.
I think that parts of Southeast Asia is a little bit more nuanced. So India has a unique opportunity here. It faces near term challenges as a consequence of the health pandemic and its ability to deal with that, but it has a very large domestic economy, it has the ability to attract capital to invest in infrastructure, that will create reinvestment opportunities for us the shareholders. And I'd also say that parts of Southeast Asia are somewhere in the middle where Indonesia relies on global trade to attract dollar inflows to fund its investment, but it also has 250 million people and a large domestic economy. So there will be opportunities in those market places but they might be still a bit more unique and specific than maybe they are broad-based elsewhere.
