Mar 8: Shell and PetroChina bid for Arrow

Royal Dutch Shell and PetroChina have underlined their desire to be big players in Australia's coal-bed methane gas sector after making a joint offer thought to be worth at least A$3.7bn (US$3.4bn) for Australia's Arrow Energy. Carola Hoyos, chief energy correspondent, talks to Daniel Garrahan about why the coal-bed methane gas company is attractive to Shell and PetroChina and why Australia's uneasy relationship with Chinese investments in its natural resources could prevent the deal going through.
