We have at least one monitoring node in South Korea, Japan, China and Taiwan. With the help of those, we gathered the traceroute results for the neighbours as well as the world as shown in the figures below.

The traceroute results (annotated, raw) originating from China show that China is directly connected to its neighbours i.e. Taiwan (#5, 61 ms), South Korea (#27, 73 ms) and Japan (#8, 100 ms) and the traffic generally takes the direct routes. However in some cases, the results show that traffic destined for South Korea is either routed via Japan (#7, 114 ms) or Japan and US (#16, 209 ms) or Hong Kong and United Kingdom (#54). Similarly, the traffic destined for Japan is routed via Hong Kong (#24, 206 ms) or Taiwan (#25, >90 ms). Also, traffic to Taiwan is sometimes directed via South Korea (#27, 245 ms). On the other hand when the destination is within China, the traffic stays within China which is what one would expect.
The results (annotated, raw) from South Korea show that Korea is directly connected to Japan (#1, 36 ms), Taiwan (#6, 214 ms), China (#11, 110 ms) and the US and the traffic generally takes the direct routes. However some results show that traffic destined for Japan is directed via the US (#23, 182 ms). Similarly, traffic destined for Taiwan is sometimes routed via the US and Australia (#2, >272 ms) and the traffic destined for China is sometimes routed via Hong Kong (#80, 97 ms). Lastly the traffic destined within Korea is observed to stay within Korea as one would expect.
The traceroute results (annotated, raw) originating from Taiwan show that Taiwan is directly connected to its neighbours Japan (#1, 34 ms), China (#17, 61 ms), Korea (#7, 45ms), Hong Kong (#63, >30 ms) as well as the United States and the traffic generally takes the direct routes. However in some cases the results show that traffic destined for Japan is routed via the US (#23, >140ms) or Hong Kong (#74, 73ms). Also, the traffic destined for South Korea is sometimes routed via Japan (#18, >65 ms). As one would expect, the traffic destined for a node within Taiwan stays within Taiwan.
Random tests to countries in the Asia showed traffic flowing as expected (i.e. as per the submarine links). However the results below were interesting. The RTT values encouraged us to conclude that traffic was indeed traversing these links.
China to Thailand: China->Hong Kong->Japan->Thailand OR China -> Thailand
China to Vietnam: China->Hong Kong-> United Kingdom->Hong Kong-> Vietnam
China to Singapore: China ->Hong Kong->Japan->Singapore
China to Malaysia: China->Hong Kong->Malaysia

Korea to Philippines: Korea -> Germany->Hong Kong->Philippines
The traceroute results (annotated, raw) originating from Taiwan show that Taiwan is directly connected to its neighbours Japan (#1, 34 ms), China (#17, 61 ms), Korea (#7, 45ms), Hong Kong (#63, >30 ms) as well as the United States and the traffic generally takes the direct routes. However in some cases the results show that traffic destined for Japan is routed via the US (#23, >140ms) or Hong Kong (#74, 73ms). Also, the traffic destined for South Korea is sometimes routed via Japan (#18, >65 ms). As one would expect, the traffic destined for a node within Taiwan stays within Taiwan.
Interestingly though, the traceroute results (annotated, raw), Japan is directly connected to its neighbours and nearly all the traffic to destinations in neighbouring countries is routed via the direct links. Random tests to countries in the Asia showed traffic flowing as expected (i.e. as per the submarine links). However the results below were interesting. The RTT values encouraged us to conclude that traffic was indeed traversing these links. It is worth noting that traffic destined for Vietnam from both China and Korea is routed via the US, when Japan is directly connected.
Japan to Thailand: Japan -> United States -> Canada -> Thailand
Japan to Vietnam: Japan -> Vietnam
Japan to Singapore: Japan -> Singapore
Japan to Malaysia: Japan -> United States -> MalaysiaInterestingly though, Japan is directly connected to its neighbours and nearly all the traffic to destinations in neighbouring countries is routed via the direct links.
