I would to add something in here. I have seen some arguments on how Indonesia should increase it's Investment with Foreign Credit line (not only in this forum, but also in other forums), as Indonesian GDP can still manage that.

I put this BI statistics on shown that Debt to GDP ratio is creeping up. From 30+% in 2019, to close to 40% in 2020, and projected toward 41%-42% in 2021. I can tell you that ratio makes us in Financial Industry and those in Financial regulators institution very nervous. Imagine if MinDef proposed USD 120+ bio foreign financing scheme being book all up front in this term (eventough stretch 25 years as some claim as the structure not clear yet), it will shoot up the external debt above 52% ratio.
Granted now Global Debt is increasing due to COVID situation. We in the Industry predicted that the debt situation can only back to normalised after 2022 or 23. However this make everyone that going to take up new credit limit whether in Government or Commercial institutions, has to calculate very carefully. Committing on credit line for long term project will be especially need to calculate carefully, on the viability of cash flow coverage years ahead.
Some argue that after COVID crisis, Global economy will have high growth for at least a decade. This arguments come from situation after great depression in 30's. However the truth is we don't know how the Global economy with still many Geopolitical challenge will work after COVID.
For that with 40+% Debt to GDP ratio, it's very understandable that people in Ministry of Finance, or Bapenas, or BI/Central Bank will be very cautious on committing to any credit schemes (whether domestic one, and especially foreign originated ones). Long term credit line has to be seen on how far this will increase the debt ratio and more importantly how far the annual installment will take up budget room. More links showing how debt ratio is creeping up.
Indonesia recorded a Government Debt to GDP of 39.30 percent of the country's Gross Domestic Product in 2023. This page provides - Indonesia Government Debt To GDP - actual values, historical data, forecast, chart, statistics, economic calendar and news.

Some in local forums or even local media argue whether the debt ratio can be increase from 40% toward 60%+. Their arguments that with Indonesia GDP already USD 1.0 Trillion + and already in #15-16 globally, we can take more. They're taking example on some countries that already has 60% even close to 100% debt to GDP ratio.
However they're forgot to see those countries have Sovereign Rating much higher than Indonesia. Indonesia sovereign rating only BBB just a notch above Investment grade, while those countries with higher Debt to GDP ratio mostly either A,AA, or even AAA rating. Your credit rating whether you're individual, commercial business or Sovereign Government will tell you how much market confidence toward you on taking debt. It's not seems fair, but that's what real world working.Typical BBB nation usually maintain their debt to GDP ratio around 30%-40%. As those links above shown, we already on that threshold.
The make up of the debt also reflect the economics situation of their population wealth. Wealthy nation's will have more domestic debt sources, cause their population have more wealth on providing domestic credit line source. As Indonesia only a middle income country, our population are not wealthy enough providing most of debt sources. Also the more wealthy your population are, the larger your Tax pool. This will come back to how much your government can provide services, including defense.
Thus for Indonesia possition, we can't provide too much Investment on defense Industry yet. They have to be build gradually reflected on how much their own government can take up the domestic defense Industry products. Because the defense Industry products customer take up will be their own government.
That's why when Habibie's in 90's ask for more Investment in strategic Industry, most of Soeharto's economics team try to pull a break on that. Because they now, Indonesian economy is not big enough to absorb all the products. Sell them abroad as new player need support from local financial institution, just like China do right now (as example). If your financial Industry is not big enough to do that, and how you're going to provide credit line?
Selling strategic Industry products like defense need credit line support.
Even with USD 1.0+ trillion economy, we are not structurally in good position yet. Our financing still much depend toward foreign Investors and Financiers. Singapore for example even with smaller economy size, but financially more independent than Indonesia, as their population tax pool and savings (as sources on domestic credit) proportionally healthier. That's why Financial regulators in Indonesia is working hard to maintain the Debt Ratio on manageable level, in order to maintain global market confidence. Because Indonesia still relatively depends on Global Investors and Financiers more.
