For context, here's the relevant paragraph
From my chats with low-level IRGC functionaries, I understood there to be a ranking of sorts as to which foreign prisoners fetch the highest price. Complete foreigners are generally more valuable than dual-nationals. Western Europe is better than Eastern Europe is better than Japan. The Chinese whisk their citizens away in a matter of months; detainees from the developing world can expect to serve their sentences in full. Americans and Israelis are the most expensive hostages to extract, and are therefore the most coveted.

This sentence highlighted in bold seems to me to be a run-on sentence. Is that a typo or maybe some structure that I don't know about？
Particularly, which is better than Japan？
