Translation of salvaguardar

I just got back from 3 very successful and intensive weeks in China. Sorry I couldn't help, but thanks for your interest. Maybe in the future we can study together with Vocabulix. Take care.
Please write me from your home as soon as your are back. My Spanish is better than that of most Americans, but my English is worse than that of most people here. It is a strange position that I am in.
After two weeks in less developed countries it was somehow interesting to arrive here. The express shuttle from the airport took us into town in less than twenty minutes and had several station.
