China draws back from role as 'all-weather friend' to Zimbabwe
BEIJING — China acknowledged Tuesday that it has slowed investment in Zimbabwe, a longtime African ally teetering on economic collapse, in a sign that it may be heeding Western demands that it quit backing regimes considered despotic.

The withdrawal of economic support from Zimbabwe's largest investor and only major global backer is a serious blow to Robert Mugabe, an 83-year-old liberation hero who has clung to power in Zimbabwe for nearly three decades
And in the same piece:

Elsewhere in Africa, China continues its free-spending campaign for resources.

The latest example came Monday in the Democratic Republic of Congo, where news reports say Chinese officials signed deals for $5 billion in loans for construction of railways, highways, universities, housing complexes and investment to extract minerals, such as cobalt, copper, gold and diamonds.
