All of our Seattle products, including dedicated servers, colocation and VPS, use the same China optimised networking if using Spartan Host IP addresses. Only exceptions are non DDoS protected IPs and L7 protected IPs (DDoS-guard - used if you select L3, L4, L7 when purchasing additional IPs) and if you choose CMIN2 instead of the default.
The default routing we use is as follows:
China Telecom + Unicom inbound (China to US) = AS4134
China Mobile inbound = China Mobile International (CMI)
China Telecom + Unicom + Mobile outbound (US to China) = AS4837

CMIN2
We also have CMIN2 routing available as an upgrade for dedicated servers and there is separate VPS plans.
CMIN2 VPS plans are here and it is selectable as an upgrade when purchasing a Seattle dedicated server in the "bandwidth" dropdown.
CMIN2 routing is as follows:
China Telecom + Unicom inbound (China to US) = AS4134
China Mobile inbound = China Mobile International (CMI)
China Telecom + Unicom + Mobile outbound (US to China) = CMIN2
