* U.S. officials see no progress on key China trade issues
* Stronger dollar, technical selling weigh on grains
* Longer term forecast projects rains in dry areas of Brazil (Adds closing prices)
CHICAGO, Jan 15 (Reuters) – U.S. soybean futures fell for the third time in four sessions on Tuesday on worries that the United States and China remain far apart in resolving a bitter trade fight that has slashed U.S. soy imports by the world’s top buyer.
Corn and wheat followed soybeans lower, with technical selling accelerating declines across grains markets.
A firming dollar, which makes U.S. exports less attractive to buyers holding other currencies, added pressure.
