Does anyone know of high-paying opportunities in China or elsewhere abroad that require an E-170/190 type (or no specific type), but ideally don't require PIC time?

I've come across Tianjin Airlines, but they appear to require 500 PIC in type, from what I can tell.

Thanks!

Short answer is no. Most Chinese jobs require a type rating with 500 PIC hours in type..However, you can apply to the likes of the ME3 or Eva Air as a first officer. Pay is better than the regionals in the USA but in all honesty why would you want to go overseas when airlines in America are all hiring. A decade ago it was a different story but today everyone in the U.S is pretty much hiring. Seniority is everything. Plus with all the turmoil in the Middle East and Asia( N.Korea), why would you even want to go there. Not so safe anymore. If you still insist, talk to the likes of rishworth aviation..Maybe they can guide you better.

One of the pilots I flew with lately was in your shoes. He, and other 170/175 FOs were doing the interview/sim for PIC -190 jobs in China. I don't know which airline...

In general true i guess. However, chinese carriers are open for cooperation on that front with other airlines. We had a program running for a while where our FOs were selected as Captains with chinese carriers, (Tianjin, Xiamen and another carrier) did their upgrade with us plus their normal linetraining (100 hours, 40 sectors) and then went on to fly as normal captains in china on A320 or 737. That way they didn't need the 500 PIC hours on type, but some hours experience on type. IIRC 4000 hours for the A320 and 1500 hours for the 737. Sadly i have no idea about something like that for the Embraers.
