Traveling to China or Russia? Better go lean and light--leave your cellphone and laptop at home and instead bring “loaner” devices, which you erase before you leave and wipe clean the minute you return.

Connect to the Internet only through an encrypted, password-protected channel, and copy and paste passwords from a USB thumb drive (never type in a password directly).

That’s ‘Business 101’ — at least it should be.” Neither the Chinese nor Russian embassies in Washington responded to several requests for comment. . . . " (emphasis added)
