Yes there is, but if there wasn't it's easy enough for a government controlled provider to advertise it (and 1.1.1.1 etc).

China (and others) can also simply intercept all udp traffic to port 53.

Which is why DNSSEC (to prevent MITM tampering) and DNS encryption technologies such as DNScrypt or DNS-over-TLS/HTTPS become ever more important to be widely deployed.

DNSSEC does little to prevent state-level intercept of DNS queries, since it's a server-to-server protocol that collapses down to a single, trivially-flipped header bit in the client/server transaction.
Doesn't really help though - even when you bypass China's DNS hijacking you still can't connect to the target IP.
