RNP 4

Is there any airspace or routes at this time that are RNP 4 exclusive. If so, where?

Thanks

A couple very busy routes within Hong Kong FIR at FL290 and higher now require RNP 4. These are routes between HKG and SIN (M771 and L642).

Eventually all enroute flights over Hong Kong must be at RNP 4 or better, with RNP 2 being phased-in soon.
