Can you reccomend good travel insurance for travel for a year from the UK to China?

I will be working in China and need to acquire good, reliable but reasonably priced travel insurance.

Try Squaremouth. It's a comparison site that specializes in long term international medical for any nationality traveling outside their home country. It's a USA based site priced in $ but the exchange rate is great for you right now.
