On March 13, 2015, a bomb from a Burmese fighter jet dropped a few kilometers across the Sino-Burmese border, killing four Chinese workers in a sugar cane field. This isn't the first time Burma (also known as Myanmar) has bombed Chinese territory during the current fighting in the Kokang region of the Kachin State. On March 8, another aerial bomb crashed into an empty house inside China (though fortunately nobody was killed or hurt in that earlier incident). The backdrop of the strikes is higher tensions between the two Asian countries, as the Burmese military, the Tatmadaw, is engaged in a widening conflict in the ethnically Chinese Kokang region, as well as wider unrest in the Kachin State at large. Ironically, some accounts state that the offending Tatmadaw aircraft were Chinese made Q-5 attack jets, though other accounts identify the aircraft as Russian made MiG 29. (China and Russia are Burma's two biggest arms suppliers.) As of writing, Nayipidaw (Burma's capital) has denied responsibility for the incident.
