Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_48980 ( "Region" text, "1950" real, "1960" real, "1970" real, "1980" real, "1990" real, "2000" real )

### Question ###
What is the lowest value for 1990, when the Region is East Asia (10 Economies), and when 1960 has a value less than 12.6?

### Accurate SQL ###

SELECT MIN("1990") FROM table_48980 WHERE "Region" = 'east asia (10 economies)' AND "1960" < '12.6'
