It can be said the main reason oil is cheap is for political reasons.

Saudi Arabia has saved up a large stash over the past few decades & it would not like its regional power states to be taken away in wake of the removal of Iranian sanctions. At least not for a while.

The Saudi oil ministry intentionally lobbied for increased production as soon as they became aware Iranian oil sanctions could be removed.

If game theory is used to analyse the situation, it serves them best to encourage the oil price to stay low & everyone else is incentivised not to cut production either.

The Japanese economy is dependent on exports of robots to China?

yes, and cars and electronics and everything else china consumes. even 7-11. you ever been to china?

I live in China, and previously in Japan. My point is that the majority of the Japanese economy is not made up of exports to China, which in turn are not in majority made up of robots, as the parent believes.

18% of their export economy is, which is a pretty large amount.
