The four-lane highway leading out of the Sri Lankan town of Hambantota gets so little traffic that it sometimes attracts more wild elephants than automobiles. The pachyderms are intelligent — they seem to use the road as a jungle shortcut — but not intelligent enough, alas, to appreciate the pun their course embodies: It links together a series of white elephants, i.e. boondoggles, built and financed by the Chinese. Beyond the lonely highway itself, there is a 35,000-seat cricket stadium, an almost vacant $1.5 billion deepwater port and, 16 miles inland, a $209 million jewel known as “the world’s emptiest international airport.”
