Do travel insurance plans cover countries with outbound travel alerts?

The government of Hong Kong launched the Outbound Travel Alert (OTA) System to help Hong Kong people understand the risk to personal safety in traveling overseas, and there are three colors, namely Amber, Red and Black to indicate the alert level. Many travel insurance plans cover countries with OTA and they usually cover trip cancellation and trip curtailment, but applicants should keep in mind that the actual compensation depends on the policy's maximum limit, while some insurance plans only cover countries with a Black Alert. In addition, not all insurance plans cover terrorist attacks, you should check the exclusions even if they have a terrorism cover.
