is China looking to export the J-10B?

This is unclear. J-10 may not be cleared for export at all by the PRC govt even if the maker CAC wanted to. FC-1 and her variants will for the foreseeable future be CACs top export fighter. AESA upgrades as well as a future semi-stealthy variant seems to be on the cards. And you have to look at the competetion. In an export market, J-10 variants will have a lot more competetion compared the FC-1 variants.

Interesting to see the J-10 finally fitted with an IRST, is it a new wholly Chinese system?

J-10B was designed with IRST in mind since day one. J-10B 1st flew in 2008 and came into service in 2013. J-10A does not have IRST, J-10B/C does.

By the way, is a new order for another 24 to 48 birds? :confused::confused::confused:

WS-15 has never powered the J-20. WS-15 is still years away. So far there have been no leaks on engine fires on the J-20 AFAIK. The article alleges that during ground testing of the WS-15 there was an explosion at one stage. I wouldn’t be surprised if such a thing happened become this is uncharted territory for China. WS-10 development also went through a lot pain intially including a 2-year halt in powering the J-11B (2007 – 2009). But they eventually got it right and the WS-10 is now pushing towards 137 – 138 kN with the latest versions (WS-10X/IPE). So yeah, maybe there was an accident/explosion during ground testing of a WS-15, but not on a J-20. J-20 still uses AL-31FN/FM variant. There are 2x prototypes flying with WS-10X/IPE.
