I got few text dumps containing a mix of china and itu MTP3 headers,
other than that I've seen international exchange traces using more
than one standard

If not, should we just have multiple DLT_MTP2_ and DLT_MTP3_ values?

That might be the way.

...although, if a trace can have a mix of packets with different standards, presumably we'd need the DLT_MTP2_MULTISTANDARD and DLT_MTP3_MULTISTANDARD values, rather than just having different DLT_ values for different standards.
