Just looking at

Wondering how can foreign bond investment be negative? You can have 0 investment, you can have positive investment, but how can value of investment be negative? Is it Bank of Japan buying back their own debt?
Edit: I get that it's a cash flow, but that doesn't explain the source of negative cash flows.
Why the down votes? I'm a newbie...
