It is claimed in the passage that the Chinese oil workers in Sudan ----.

Since 1993, China has invested in more than fifty oil and
gas projects in some thirty nations. In particular, China has
focused on acquisitions and partnerships in Sudan and
Iran. In Sudan alone, China has reportedly spent $15
billion developing oil fields. In the meantime, China has
also begun to use its military to protect its oil investments
abroad. Reportedly, troops disguised as oil workers patrol
Chinese oil infrastructure in Sudan. Moreover, in recent
years, China has strengthened its military presence in the
oil-and gas-rich parts of the South China Sea, over which
sovereignty is still disputed. Perhaps most significant in the
short term is China's relationship with Iran. With Saudi
Arabia and Iraq clearly within the American sphere of
influence, China has been steadily courting Tehran and
aims to become the biggest buyer of Iranian oil. In return
for oil, China has supplied Iran not only with conventional
weapons but also with technology and materials that can
be used for the manufacturing of nuclear weapons.
